Sample Description

Most analyses contain small amounts of Na, but a complete solid solution series is possible from orthoclase toward intermediate albite. Crystallizes at intermediate temperatures and has a partially ordered Al-Si distribution. Grain size fractions are indicated by the extension after the sample number: .1B = IMAGE_OF_SAMPLE:
