Here is the corrected text: Raw Gabbro Specimen - Single Sample, 1" Gabbro forms within magma chambers, deep within the earth, where iron-rich rock melt accumulates, too heavy to reach the surface. As the melt cools, olivine and plagioclase feldspar form. This specimen is a great example of phaneritic mafic rock, making it useful for exercises in identifying and classifying igneous rocks. While each specimen will vary slightly in shape, size, and color, it measures approximately 1" in length. Each is individually packaged, labeled, and barcoded for easy identification and storage. Selected and processed by a geologist, each and every specimen exhibits defining features. Rocks and minerals are sourced from various locations around the world and are hand-processed in Victor, NY.
