Qap ternary diagram
These sediments were changed into metamorphic rocks due to convergence of tectonic plates, along a subduction zone (see Figure 1), that created heat, pressure, and the presence of rock-altering fluids, including those that contained gold. The oldest of these rocks, known as the Shoo Fly and Calaveras Complexes, were initially sediments deposited up to 400 million years ago, onshore and offshore, along the edge of the continent that existed at the time. Some of the oldest rocks in the Sierra Nevada are the metamorphic rocks in the foothills. We can still understand the geology of the Sierra in terms of these general groupings.
#Qap ternary diagram series
Superjacent series rocks included the younger volcanic rocks mainly found deposited upon some of the granitic rocks of the high country.
#Qap ternary diagram plus
The Subjacent series included the granitic rocks most people think of when traveling through the high Sierra, plus the metamorphic rocks of the Mother Lode gold country. The first geologists to research this region grouped the rocks into 2 main categories: 1) the Subjacent Series and 2) the Superjacent Series. The geology of the Central Sierra Nevada Mountains consists mainly of igneous and metamorphic rocks with lesser amounts of sedimentary rocks. Once the general geologic history is mastered, the " BACKGROUND" section can be skipped, if desired, and the EarthCacher, focusing on that particular part of the story, can scroll to the next section to work each specific EarthCache's " GEOLOGY" section without having to read the entire " Central Sierra Geologic History"again.Įnjoy learning more about the Geosciences and the geology of the Central Sierra Nevada! EarthCachers will visit locations highlighting the main geologic evidence supporting claims made by geologists, who have constructed the geologic history of this area, telling the amazing story that has unfolded over the past 400 million years. The series consists of approximately 20 EarthCaches in both Tuolumne and Calaveras Counties. Additionally, the science of geology, the thinking skills geologists use, and the types of career opportunities are also part of the series. This EarthCache is one of a series in Tuolumne and Calaveras Counties, intended, primarily, to inform EarthCachers about the geology and geologic history of the Central Sierra Nevada Mountains. If a response is grossly inaccurate, you will not receive credit for the cache.
