Magmatic inclusions in silicic and intermediate volcanic rocks Magmatic inclusions in silicic and intermediate volcanic rocks
Fine‐grained ellipsoidal inclusions from a few millimeters to over l m in size are present in many intermediate to silicic lava flows and domes. Only recently has it become widely accepted that such inclusions are chilled blobs of magma. Their magmatic origin is manifested by vesicularity and high groundmass porosity, by ellipsoidal shapes, by mingling at contacts with the host, and by...

Deformation of poorly consolidated sediment during shallow emplacement of a basalt sill, Coso Range, California Deformation of poorly consolidated sediment during shallow emplacement of a basalt sill, Coso Range, California
A 150-m-long, wedge-shaped unit of folded and faulted marly siltstone crops out between undeformed sedimentary rocks on the north flank of the Coso Range, California. The several-meter-thick blunt end of this wedge abuts the north margin of a basaltic sill of comparable thickness. Chaotically deformed siltstone crops out locally at the margin of this sill, and at one locality breccia...
