Document Summary
On the afternoon of thursday, october 8th, the bus left to cantley, quebec. During that day the weather was cloudy but no rain and the class observed the metamorphic rocks that have been exposed during wisconsinan glaciation period. Erosional structures such as the rat-tail and striations we found on the smooth rock bodies. The metamorphic rock that was observed was marble and was formed from the grenville orogeny. The lab coordinator placed couple of drops of hcl on the marble to see if calcite was present and it did react to the liquid hcl. To recognize in the field the effect of continental glaciation. To build a local geological history of glaciation and deglaciation. Instructions: the rock that created the bedrock is marble with some parts that consists of xenolith. The marble rock was formed from the grenville orogeny and the protolith was limestone, which means the marble is made up of calcite.
