Mine Info

Satelite View

MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments

Comment (Deposit): DIKES ARE RELATED TO TWO BUTTES LACCOLITHIC STOCK CLASSIFIED AS BIOTITE ANDESITE (?) PORPHYRY OF POSSIBLE LATE MIOCENE AGE. SANDERS' MAP SHOWS SEVERAL DIKES ACROSS COUNTY LINE IN BACA COUNTY. ; INFO.SRC : 1 PUB LIT

Comment (Geology): HILLEBRAND WED THE TERM SYENITE, BUT SANDERS REFERRED TO IT AS BASALT. INSUFFICIENT CHEMICAL ANALYSES TO CLASSIFY IT EXACTLY.

Comment (Location): 15 MILES NORTHEAST OF TWO BUTTES RESERVOIR

Comment (Commodity): PYROXENE ANALYSIS YIELDED 0.043% V205; 0.036% V203; 51.5% SIO2

Comment (Deposit): APPROX. 50 DIKES REPORTED IN THE AREA. CRUDELY DISCERNIBLE SUBRADIAL ORIENTATION OF DIKES FROM TWO BUTTES LACCOLITHIC INTRUSION.
