JA Daily Science Report for Expedition 307, 5 May 2005
LOCATION: Site U1317 (PORC-3A)
Cores U1317D-4R to 15R (136.2-241.9 mbsf), are calcareous green-grey siltstones, increasing in lithification downhole. RCB coring has proved to be faster and produce less core disturbance than XCB in this material. Cores U1317D-1R to 3R (110.0-136.2 mbsf) had only limited recovery.
