Comments on the geologic information

  • REGIONAL GEOLOGY

    The Butte Creek District is situated at the westernmost edge of the Sierra Nevada geologic province where it adjoins the Sacramento Valley This province is characterized by extremely complex lithologies and structures that were assembled through various plate-tectonic processes.

    Paleozoic-Mesozoic metamorphic complexes intruded by various Mesozoic plutons compose the basement of the province. This basement is overlain at higher elevations by erosional remnants of Cenozoic volcanic and sedimentary rocks, including gravels. Most of these various lithologies contain gold in places. In the vicinity of Chico where the province meets the Sacramento Valley, continental volcanic rocks of the Pliocene Tuscan Formation are exposed.

    Structurally, the metamorphic rocks and some of the plutonic rocks of the basement have been deformed by folding and faulting. The major fault zones typically trend northerly or northwesterly, although in places intrusion of the younger plutons has deformed some of the zones so as to assume other trends as well. In contrast, the overlying Cenozoic rocks are relatively undeformed except that the Tuscan Formation exhibits abundant fracturing, which largely trends northwesterly.

    LOCAL GEOLOGY

    The Butte Creek District is mainly associated with modern alluvial deposits of the main drainage of Butte Creek where it discharges into the Sacramento Valley after passing through the Tuscan Formation. The materials in these deposits have been derived by erosion of the various basement and older Cenozoic rocks at higher elevations as well as from the Tuscan Formation. In places, the basement rocks contain gold within quartz veins and altered rock, while the Cenozoic deposits at higher elevations contain placer gold derived by erosion of these basement rocks. Erosion of both the gold-bearing basement rocks and the older Cenozoic rocks provided the gold that was eventually deposited in the modern placer deposits along the lower segments of Butte Creek.

Mining district

District name Butte Creek District

Comments on the workings information

  • Most mining in this district was accomplished through surface placering and dredging. Some hydraulic and drift mining took place in the Tertiary deposits. Dredging depths ranged from 13 to 35 feet on an uneven bedrock surface.

Comments on other economic factors

  • The last operations were reported to have yielded as much as $0.35 of gold per cubic yard ($35/oz. price). Total production from this district is uncertain, but was likely not major.

Comments on development

  • The streams were placer-mined during the gold rush, and hydraulic mining and some drift mining of the Tertiary gravels followed. Later, the main production in the district came from mining of the lower segments of the creek, mainly by dredging. In the early 1900?s, the creek was worked with primitive power shovels and washing plants. It was then dredged from around 1902 to the early 1920?s, again in the 1930?s, and from 1945 to 1949.

General comments

Subject category Comment text
Deposit The deposits consist mainly of stream and bench gravels in and along Butte Creek. They range from a few hundred feet wide at the northeast end of the district to nearly a mile at the southwest end. The gravels are coarse, well rounded, and consist of andesite with some chert and minor quartz. There are also some auriferous Tertiary gravels in the northeast part of the district.

O?Brien (1949) reported the Butte Creek channel in Section 35, T22N, R2E to be about 250 feet wide, with the gravel about 15 feet thick above a hard tuff bedrock.
