Book excerpt: Excerpt from Mineral Resources of the Agua Tibia Primitive Area, California The Agua Tibia Primitive Area includes about 43 square miles of the Cleve land National Forest in San Diego and Riverside Counties near the Pala and Rincon pegmatite districts. The area contains Agua Tibia Mountain, which rises about feet higher than the adjacent lowlands. Most of the moun tain is covered by dense brush. Small stands of timber are present on the crest of the mountain and at the bottoms Of canyons. The principal rocks Of the primitive area are crystalline and consist of both metamorphic and plutonic varieties. The metamorphic rocks have been correlated with both the Bedford Canyon Formation and the Julian Schist of Jurassic or Older age. The plutonic rocks include San Marcos Gabbro, Bon sall Tonalite, and Woodson Mountain Granodiorite Of Cretaceous and per haps Older age. Pleistocene and younger sedimentary deposits, chiefly Temec ula Arkose Of Mann fanglomerate, and terrace deposits, cover much of the north and west perimeter of the area. The Temecula Arkose and other rocks are cut by faults, the largest of which are part of the Elsinore fault zone. NO economic mineral deposits were found during the reconnaissance study of the primitive area. Analyses of more than 100 samples of stream sediments and bedrock collected in and adjacent to the area did not indicate the presence of geochemical anomalies commonly associated with economic mineral deposits. Magnetic anomalies detected by an aeromagnetic survey are believed to be related to gabbroic bedrock and not to economic deposits of magnetic minerals. NO prospect pits or mines were seen, nor did a search of legal records reveal the existence of past or present mining claims in the primitive area.
