Precambrian Geology, Midcontinent Rife, Volcanic Rocks
We analyzed welt cores and cuttings from deep wells into Precambrian igneous rocks from five separate pacts of the buried Midcontinent Rife System in Iowa for major and trace elements. A total of 21 samples, 9 cores and 12 cuttings, were analyzed for trace elements by instrumental neutron activation analysis (INAA) and 11 of these, 9 cores and 2 cuttings, were analyzed for major elements by inductively coupled plasma (ICP) analysis.
