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...

Lithic breccia and ignimbrite erupted during the collapse of Crater Lake Caldera, Oregon Lithic breccia and ignimbrite erupted during the collapse of Crater Lake Caldera, Oregon
The climactic eruption of Mount Mazama (6845 y.B.P.) vented a total of ∼50 km3 of compositionally zoned rhyodacitic to basaltic magma from: (a) a single vent as a Plinian pumice fall deposit and the overlying Wineglass Welded Tuff, and (b) ring vents as ignimbrite and coignimbrite lithic breccia accompanying the collapse of Crater Lake caldera. New field and grain-size data for the ring...

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...
