| Text Description: | Sample of juvenile block from block-and-as flows deposited on the debris avalanche formed during flank collapse of ancestral Mt. Spurr (“pyroclastic fan”; sample PF-01 of Nye and Turner (1990). Finely vesicular plag, cpx. Plag ~0.5 mm equant - perhaps like Pakushin (snowflake). Flow contains these bread-crusted blocks and radially fractured blocks. Blocks to 2 meters. Flow also contains older reddishly-altered rounded to angular blocks. These older blocks NOT breadcrusted or radially fractured. B&A flow appears to be channel fill in older previously altered debris avalanche material. |
