JA Daily Science Report for Expedition 307, 1 May 2005

LOCATION: Site U1316

SCIENCE UPDATE: Cores U1316A-12X to 21X are lower Miocene greenish grey colored siltstones, with grain size generally decreasing downhole. The siltstone is rich in glauconite and yields microfossils (calcareous nannofossils and foraminifers) and mollusks. Hole U1316A was terminated at 134 mbsf with Core 21X on deck at 20:00 hr, and was prepared for wireline logging.
