Structure: Mcanulty (1978) Indicates That The Tortugas Mine Lies At The Western Rim Of The Resurgent Organ Mtn Caldera. The Vein Occurs In A N 07 W Striking Fault Zone; Also Faults Trending N 30 E And N 50 W

Tectonics: Basin And Range

Deposit: No data is given for the santiago vein except that it is located about 800 ft west of the tortugas vein. Record # d009951 by jerry l. Haug has been incorporated into this record. ; info.src : 1 pub lit deposit consists of veins, veinlets, pods, and breccia cemented by fluorspar in a north-trending fault zone. The principal orebody was stoped along strike for a length of 600 ft. Near the surface and for a length of 300 ft. At a depth of 386 ft... The orebody is up to 13 ft. Thick but averages about 4 ft. Thick.. Five unpatented claims reported in 1928. At the tortugas vein fluorite occurs As white or pale green medium to large cubic crystals As vein filling in fissures. Calcite, quartz, and limestone wall rock inclusions accompany the fluorite. 600 ft north of the shaft, the tortugas vein crosses a flatter dipping N 30 E trending vein, northeast of which only sporadic fluorite occurs. The jones vein, located 600 ft east of the tortugas, trends N 50 w. Fluorite is found there in a breccia body on the northwest side of a shaft.

Development: Mine was leased and operated by charles f. Johnson from 1919-1921 and several lessees until 1942 when it was acquired by j.k. Stanland.

Geology: Between 400 and 500 ft of massive bedded, gray to dark gray, siliceous limestone and shale of the pennsylvanian magdelena group make up the tortuga mountain fault block. The beds dip to the west and are bounded on the east by a north-striking fault and on the northeast by a N 55 W striking fault.

Rock formation(s): Magdalena Group


Ore(s): Fault-Fracture Structural Control.
