Mechanisms and Rate of Emplacement of the Half Dome Granodiorite
Mechanisms and rate of emplacement of the Half Dome Granodiorite Kyle J. Krajewski Chapel Hill 2019 Approved by: Allen F. Glazner Introduction Continental crust is largely composed of high-silica intrusive rocks such as granite, and understanding the mechanisms of granitic pluton emplacement is essential for understanding the formation of continental crust. With its incredible exposure, few places are comparable to the Tuolumne Intrusive Suite (TIS) in Yosemite National Park for studying these mechanisms. The TIS is interpreted as a comagmatic assemblage of concentric intrusions (Bateman and Dodge, 1970). The silica contents of the plutons increase from the margins inwards, transitioning from tonalities to granites, through both abrupt and gradational boundaries (Bateman and Chappell, 1979; Fig. 1). The age of the TIS also has a distinct trend, with the oldest rocks cropping out at the margins and the youngest toward the center. To accommodate this time variation, the TIS is hypothesized to have formed from multiple pulses of magma (Bateman and Chappell, 1979) . Understanding the volume, timing, and interaction of these pulses with one another has led to the formation of three main hypotheses to explain the evolution of the TIS. Figure 1. Simplified geologic map of the TIS. Insets of rocks on the right illustrate petrographic variation through the suite. Bateman and Chappell (1979) hypothesized that as the suite cooled, it solidified from the margins inward. Solidification of the chamber was prolonged by additional pulses of magma. These pulses expanded the chamber through erosion of the wall rock and breaking through the overlying carapace, creating a ballooning magma chamber. -

Tuolumne Meadows the Beautiful Rounded Domes of Tuolumne Meadows Offer Some of the Best Moderate Granite Climbing Any- Where
TM most practical multi-pitch solution v1.0 Tuolumne Meadows The beautiful rounded domes of Tuolumne Meadows offer some of the best moderate granite climbing any- where. Located within the Yosemite National Park, Tuolumne is a good choice if you want to escape the heat and the crowds of the Yosemite Valley, and climb in a peaceful and quiet setting during the summer months. Tuolumne is simply an amazing place of solitude and beauty, where exquisite climbing opportunities await on some of the best granite in North America. The massive granite domes and other high peaksMt areOlympus situated at an altitude of 8600 feet, where the air is cool and crisp, and the skies are clear. Tuolumne is more peaceful, relaxing, and quiet than the Valley, and you’ll be happy to be climbing in a cool alpine breeze when it’s 100+ degrees everywhere else. After a long day of climb- ing on perfect glacier polished granite, go take a hike accross the meadow, hang out at the beach at Tenaya Lake, cool down in the river or enjoy a local beer and a burger at the grill. Tuolumne Meadows is simply the perfect summer climbing destination.

BEDROCK GEOLOGY of the YOSEMITE VALLEY AREA YOSEMITE NATIONAL PARK, CALIFORNIA Prepared by N
DEPARTMENT OF THE INTERIOR TO ACCOMPANY MAP I-1639 U.S. GEOLOGICAL SURVEY BEDROCK GEOLOGY OF THE YOSEMITE VALLEY AREA YOSEMITE NATIONAL PARK, CALIFORNIA Prepared by N. King Huber and Julie A. Roller From the writings of Frank C. Calkins and other sources PREFACE INTRODUCTION Frank Calkins' work in Yosemite was preceded by Yosemite Valley, one of the world's great natural works Henry W. Turner, also of the U.S. Geological Survey, of rock sculpture, is carved into the west slope of the who began mapping the Yosemite and Mount Lyell 30- Sierra Nevada. Immense cliffs, domes, and waterfalls minute quadrangles in 1897 and laid the foundation that tower over forest, meadows, and a meandering river, Calkins' work was built on. Although Turner never creating one of the most scenic natural landscapes in completed this sizable assignment, he recognized the North America (fig. 1). In Yosemite Valley and the differing types of plutonic rocks and, for example, named adjoining uplands, the forces of erosion have exposed, the El Capitan Granite. with exceptional clarity, a highly complex assemblage of Calkins mapped the valley and adjacent areas of granitic rocks. The accompanying geologic map shows the Yosemite National Park during the period 1913 through distribution of some of the different rocks that make up 1916, at the same time that Francois Matthes was this assemblage. This pamphlet briefly describes those studying the glacial geology of Yosemite. Calkins rocks and discusses how they differ, both in composition summarized the bedrock geology of part of Yosemite in and structure, and the role they played in the evolution the appendix of Matthes' classic volume "Geologic History of the valley.
