age).
Fall 2005
Rio Grande
city, Roma and San Ygnacio
Why are
we going there?
we will be
visiting various rock outcrops and unconsolidated sediment deposits all along
the 83 highway from
Sullivan
city to San Ygnacio. The students will learn to describe and interpret rocks in
the field and make
measurements
using Brunton compass. Students will make observations about the grain size,
roundness, sorting,
mineralogy,
degree of cementation, and sedimentary structures. Students will learn a
great deal about the
depositional
environment of these rocks and sediments. River processes will also be
studied using the examples
from Rio
Grande.
