A Ag-Cu prospect located in sec. 19, T2N, R25E, SBM, 5.5 km (3.4 miles) N of Vista Peak (coordinates of record), on Bureau of LAnbd MAnagaement administered land. MRDS database stated accuracy for this location is 10 meters. This property is No. 17 in the Whipple Mountains report.
This property was examined in conjunction with the mineral appraisal of the Whipple Mountains Wilderness Study Area (Bureau of Land Management) in 1980. Backup information can be found in the WFOC mineral property files.
The ore body strikes N85E and dips 23W. Ore body No. 1 is tabular in a shear zone. ore Body No. 2 is irregular. The primary mode of origin was hydrothermal activity and the secondary mode was oxidation. Primary ore control was faulting and the secondary control was fracturing. Wallrock alteration is slight (propylitic). Local rocks include Precambrian igneous and metamorphic rock complex.
2 valid minerals.
This information on rock units at or nearby to the coordinates given for this locality is based on relatively small scale geological maps provided by various national Geological Surveys. This data will improve over time as more accurate maps and data sets are added.
|Miocene - Paleoproterozoic5.333 - 2500 Ma||Precambrian igneous and metamorphic rock complex|
Present only in southern California
|Precambrian541 - 4000 Ma||Precambrian metamorphic and undivided crystalline: undivided crystalline rocks (seafloor units may include a variety of metamorphosed rock)|
Metamorphic and undivided crystalline: undivided crystalline rocks (seafloor units may include a variety of metamorphosed rock)
|Paleoproterozoic1600 - 2500 Ma||Paleoproterozoic intrusive and metamorphic terranes|
Intrusive and metamorphic terranes
Mixtures of metamorphic and intrusive or plutonic rocks, tracts known as crystalline, migmatitic terranes, moderately to highly metamorphosed rocks of unknown origin with or without intrusions. This classification is inherently prone to variable interpretation, as other compilers might distinguish some packages by their metamorphic or gneissic protoliths, and the associated age ranges may be more variable.
