Abstract: Lechuguilla Cave is a hypogene cave formed by oxidation of ascending hydrogen sulfide from the Delaware Basin. A unique sediment deposit with characteristics suggesting derivation from the l...
Third Hutton Symposium: The Origin of Granites and Related Rocks. Edited by M. Brown, P.A. Candela, D.L. Peck, W.E. Stephens, R.J. Walker, and E. Zen. Geological Society of America Special Paper 315, 1996
Origin of Granites Related Rocks Geological Society America Special Paper
2012/3/31
The controversies surrounding granites never seem to die.
Two hundred years ago a debate raged over whether granites are
sedimentary or igneous. With James Hutton effectively putting
that one to re...
