A former Sn occurrence/mine located in secs. 1, 2, 3, 10 & 11, T4S, R6W, SBM, 5.5 km (3.4 miles) ENE of El Cerrito, about 5 miles SE of Corona and about 11 miles SW of Riverside. MRDS database stated accuracy for this location is 1,000 meters. First produced in 1869 and last in 1928.

Mineralization is a vein deposit. Local rocks include Mesozoic granitic rocks, unit 2 (Peninsular Ranges). The vein was followed to 650 feet of depth but had not bottomed out.

Workings apparently include underground openings in view ofd mthe fact that the vein was followed to 650 feet of depth.

Late Cretaceous - Middle Jurassic
66 - 174.1 Ma



ID: 2940938
Mesozoic granitic rocks, unit 2 (Peninsular Ranges)

Age: Mesozoic (66 - 174.1 Ma)

Stratigraphic Name: Bonsall Tonalite; Bradley Granodiorite; Cactus Quartz Monzonite; Cajalco Quartz Monzonite; Corona Hornblende Granodiorite Porphyry; Domenigoni Valley Granodiorite; Escondido Creek Leucogranodiorite; Estelle Tonalite; Fargo Canyon Diorite; Green Valley Tonalite; Home Gardens Quartz Monzonite Porphyry; Indian Mountain Leucogranodiorite; Lakeview Mountain Tonalite; Lake Wolford Leucogranodiorite; La Sierra Tonalite; Mount Hole Granodiorite; Rattlesnake Granite; Roblar Leucogranite; San Jacinto Granodiorite; Stonewall Quartz Diorite; Woodson Mountain Granodiorite

Description: Mesozoic granite, quartz monzonite, granodiorite, and quartz diorite

Comments: Peninsular Ranges. Primarily tonalite, granodiorite, and minor quartz monzonite and granite. Emplacement ages mostly 80 to 105 Ma in eastern part of area and 105 to 140 Ma in western part; minor Jurassic rocks in central part Original map source: Saucedo, G.J., Bedford, D.R., Raines, G.L., Miller, R.J., and Wentworth, C.M., 2000, GIS Data for the Geologic Map of California, California Department of Conservation, Division of Mines and Geology, CD-ROM 2000-07, scale 1:750,000.

Cretaceous
66 - 145 Ma



ID: 2245112
Cajalco Pluton: Monzogranite

Age: Cretaceous (66 - 145 Ma)

Description: Most of western part of pluton is medium-grained, equigranular, hypautomorphic-granular to subporphyritic monzogranite and subordinate granodiorite. Includes variable amounts of angular inclusions, mostly, if not entirely derived from stoping of Estelle Mountain volcanics of Herzig (1991). Number, size, and reliability of idenity of inclusion parent rock increases from east to west. In western part of pluton included masses of volcanic rock comprise large volume of pluton. In northern and northeastern part of pluton stoped masses of hornblende gabbro are abundant. Unit includes relatively fine- grained leucogranite, especially in area northwest of Lake Mathews
