The clay minerals occurring in caves of the Guadalupe Mountains of New Mexico include kaolinite, dickite, hydrated halloysite, illite, montmorillonite, trioctahedral smectite, and palygorskite. The minerals associated with ...
Geology and petrology of Cretaceous and Tertiary granitic rocks, Lamoille Canyon, Ruby Mountains, Nevada
(Texas Tech University, 1999-05)
Lamoille Canyon cuts through the northern Ruby Mountain metamorphic core complex and exposes the deep interior, which is characterized by highly metamorphosed miogeoclinal sedimentary rocks and various late Cretaceous and ...
Magmatism associated with extension, Harrison Pass Pluton, Ruby Mountains, Nevada
(Texas Tech University, 1996-08)
The objectives of this study are: (1) to describe in detail the Tertiary rock units exposed in the Harrison Pass pluton, (2) to use geochemical and isotopic data to constrain the petrogenesis of Tertiary granitic rocks in ...
Soil-geomorphic relationships in the ancient Lake Lomax Basin, Southern High Plains
(Texas Tech University, 1999-08)
The Lake Lomax Basin is on the southern margin of the High Plains in West Texas. Evidence suggests that it has been formed by subsidence/erosion processes in very eariy Pleistocene time and subsequent wind deflation. This ...
