  Morro RockExample 1Igneous RockMorro rock is a Volcanic Plug which is approximately 22 to 23 million years old. According to San Luis Obispo quarries history it classifies the rock to be granophyre. Granophyre is a fine grained granite rock in which irregular crystals of intergrown quartz and feldspar are embedded in a groundmass of these minerals

  Igneous RocksExamples 2and3These rock were found while walking along the embarcadero in Morro Bay.I believe the light colored rock to be Scoria and the darker colored rock to a Gabbro. Both are considered igneous rock. Scoria is an extrusive igneous rock. The vesicles are formed from the release of trapped gas within the melt at the time of solidification.Gabbro is an extrusive igneous rock and is abundant in the deep ocean crust.
