LITHOPHILE ELEMENT MINERALIZATION ASSOCIATED WITH LATE
CRETACEOUS TWO-MICA GRANITES IN NEVADA AND CALIFORNIA
BARTON, Mark D., Department of Earth and Space Sciences, UCLA, Los
Angeles, CA 90024

Late Cretaceous (69-86 m.y.) strongly peraluminous two-mica granitoids
are intimately associated with an unusual style of lithophile element
mineralization. Eight areas with characteristic mineralization have
been identified in a region stretching from eastern Nevada to eastern
California roughly corresponding to the axis of the Cordilleran miogeo-
cline. Alteration is typified by strong F and Al metasomatism. Skarns
are typically stockworks with the sequence (early to late): gt+cpx=id±
fl-pc+fl+ep+amph+chl±cz-bizap-mu+fl+phl±carb-ap-qz+mu+fl-carb (-Ag-bear-

ing qz+carb veins). Ore minerals (found with hydrous skarn) include:
sph, py, po, sch, mol, beryl, phenakite, bertrandite and ccp. In
clastic rocks, qz veins contain py±muflisch. The intrusives commonly
contain abundant aplites, pegmatites and qz veins (beryl-wolf±mol:
greisen envelopes) with lesser amounts mu+fl greisen and albitization.
Grades can exceed 25% CaF2, 4% Zn, 1% Be0, 1% W, 0.5% Mo, and 500ppm Sn.
The McCullough Butte, Nevada area contains >10 tons of >10% CaF2. This
style of mineralization resembles lithophile element ore deposits in
Asia, Australia and Alaska.

i

Field relations and available stable isotope data indicate magmatic components in the F-rich alteration with or without minor meteoric/ connate/host components. The intrusions have some characteristics of a reduced, sedimentary source: 6160(w.r.) = 9.1-13.4., (7Sr/Sr); = 0.711-0.737, Ca0+ Mg02 wt%, and low opaques. Other features are incompatible with a highly evolved source (or magma). Rb/Sr 0.5, La/Yb 10, and Eu/Eu* > 0.7. The high F content and high-Al mobility in these deposits may result from the low Ca + Mg contents and high Al (Na+K+Ca) in the igneous rocks, in turn reflecting the sources and evolution of the magmas.

Senator HECHT. I thank you.

Just one question. Carl, Bill Farr from Reno and Pete Kelley from Carson have been out talking to you, have they not, trying to work out, on my staff, your boundary lines?

Mr. BAKER. They have talked with my brother, yes.

Senator HECHT. With your brother?

Mr. BAKER. Yes, sir.

Senator HECHT. We have made every attempt to try and work out the different boundary lines, and your water rights, and everything.

Mr. BAKER. Yes, and we certainly appreciate those efforts, but it is very difficult for us to go with the concept that hurts our neighbor.

Senator HECHT. I see.

Mr. BAKER. This will have a major impact on the Gondors, and we just cannot go along with something that really hurts the people we live and deal with every day and that are good friends.

Senator HECHT. I appreciate that, and thank you very much. Thank all of you for coming to Washington to testify.

Let us go right on now. Dr. Robert Starr Waite; Mr. Darwin Lambert; Mr. George Lea; Mr. Charles Callison; and Robert Jacob

sen.

Dr. WAITE. Senator?

Senator HECHT. Yes.

Dr. WAITE. Could I request that Ann bring in the topographic relief map of Nevada?

Senator HECHT. Of course. I have not seen you since Ely, right? Dr. WAITE. Yes. It is great to see you again.

Senator HECHT. Thank you very much.

Dr. Waite. Tell me, are you feeling better since then?

Dr. WAITE. Why, I am feeling great.

Senator HECHT. You remember you kind of scared us a little bit that day.

Dr. WAITE. I was so excited by your hearings that, you know, I became overcome with emotion.

Senator HECHT. OK, please start in.

STATEMENT OF DR. ROBERT STARR WAITE, UNIVERSITY OF

UTAH, SALT LAKE CITY, UT

Dr. WAITE. OK, I have tried to bring something to you today that will tell you the Great Basin story over the past 62 years. This is easily a world record for National Parks.

What I have done here is I have given you about seven different items, and perhaps I could have-maybe I will just hold these up for you. This first one that I have for you, this is the color version right here, it was done 25 years ago when they were trying to create a park in Nevada. This is worth its weight in gold. I keep this in the family vault.

Anyway, here is the story of the Great Basin. I have updated it now to 1968, the current year with another document. The one I am going to read from is called "Proposed Great Basin National Park," and I will be using this one. I have also included one that is "Great Basin Science." I have gone in here to the master plan for a

Great Basin National Park, plus geology, climatology, history, archeology, botony, zoology, the Great Basin and Science.

My doctoral dissertation has been claimed as junk, but if it is junk then the University of California is junk, and the 25 professors who read it are junk. So I might relate to Joe that he might look up where the Bergstrun is to prove that this is a glacier. He might look up the fact that permafrost is not tundra. And he might look up one or two other things where he has some errors.

Joe is a good friend, though. In fact, Joe has a quote in one of the Great Basin books that says up on Mount Washington, it says, is nature's art gallery to walk through the bristlecone forest.

I have also included the first hearings from Senator Reid which includes the story of the bristlecone pine, and also some other significant things, the history of the Park movement, and the value of the Great Basin National Park. Then I have also included a Silver Circle document here that would tie the whole recreational economy-this is going to President Reagan; this is in color. We have 156 versions of this from a school in Utah, but this would tie the whole Great Basin recreational economy to Ely and the Great Basin.

Quickly let me just run through some of the highlights of this. The Great Basin is big, and the Great Basin is impressive, and it is the only place like it in all of North America or South America. The thing that makes it so unique is it has over 300 mountain ranges-300. What we are asking for is one small section of one to tell the story of a region the size of France.

The Southern Snake range has a lot of attractions, and you have heard of all of this. I have listed these below here, but basically the range is divided up into six sections. This is part of a 150-mile mountain belt that runs along the Utah-Nevada State line. We are asking for a little tiny whimpering area to tell the Great Basin story.

I have listed one thing in here. I have listed under the Wheeler Peak area, of these six major mountain peaks, I have listed that the bristlecone is 5,125 years old. When they cut the tree in 1964, which should never have been cut, they counted 4,900 rings. But what people do not realize is that every 100 years it is either too dry or too cold and bristlecone pine will not add a ring. So this tree is easily well over 5,000 years old, and the oldest one in the Great Basin. Of course there are other ranges

Senator HECHT. I will have to ask you to summarize. Your 5 minutes is up.

Dr. WAITE. OK. I talk about bristlecone on the next page. I should think it should have a National Park home. I think it should belong to the World Heritage Foundation of outstanding natural features.

On page 3, a world record. The dissertation I wrote, if anyone wants a copy, 52 copies are being printed. If anybody wants a copy of the $80,000, $60,000 study the Park Service did, I have these. If you want to see what the Great Basin really is like, I brought over 500 slides. If anybody would like to look at just one, this will tell the Great Basin story.

Finally, I might say that there is a beautiful network of roads here. There are six beautiful campgrounds of table water, cooking facilities, restrooms, and I think we should name the visitor's

center the Laxalt Visitor's Center. We could have a Hecht Great Basin Scientific Center. We could have a Vucanovich Bristlecone Pine study area. We could have a Mount Reid at 11,800 feet. I tell you, there is room for everybody here. [Laughter.]

Senator HECHT. I have to stop you. That is enough. But I thank you for your kind consideration, Doctor, but we have to go right on. Dr. WAITE. Could I just add one thing?

Senator HECHT. Sure.

Dr. WAITE. I think I have got two factors here-I think No. 5 where I say "park size," and I want to read this. I think this is the most important factor: Whether a park is 44,000 acres or 129,500 acres, the size is unimportant. The story the park has to tell, and not its area, shape, or size, is the most important thing.

Examples of some of our smaller parks such as Hot Springs, 5 million visitors a year; Virgin Islands, over 700,000; Haleakala, over a million; Wind Cave, half a million; Bryce Canyon now approaching 800,000; Carlsbad Caverns, 700,000; Mamouth Cave, over a million. These are all smaller, you see, and they have great potential.

Senator HECHT. This is not fair to the other people who have also come a long way, so I am going to have to cut you off, Doctor, but I thank you very much.

Dr. WAITE. Could I just say, thank you, Senator Hecht, and I would take the 44,000 acres and run with it. If we do not get a park this year, we will not get it, and we are going to lose another $100 million in the State of Nevada.

Senator HECHT. Thank you.

Dr. WAITE. And I appreciate the consideration of coming into Washington and attending this conference, and let us get a Great Basin National Park in 1986.
