Document Summary
The field excursion lab included going to two different locations which were the carlisle. While doing this excursion there were certain details noted which will be discussed in the following report. The quarry has been estimated to have come to form during the carboniferous age which was 360-310 million years ago. The quarry consists of igneous rock and sedimentary rock. The types of rocks included basalt, conglomerate, lithic sandstone, chert, quartz and calcite. Physical appearance of the rocks were red/brown which is from weathering over time, and some of the rocks consisted or quartz and calcite in their vesicles which are air holes that form overtime. Lithic sandstone fragments were volcanic and some rocks had honeycomb pattern which are mud cracks from body of water drying out. Basalt made out the layers that stand out which are very hard and dense due to the fact that they are plagioclase and pyroxene. b. )
