Clay minerals at DSDP Sites 71-511 and 71-513
The distribution of clay minerals, determined by X-ray diffraction, is given for Jurassic to Holocene sediments recovered at DSDP Sites 511 and 513 in the Southwest Atlantic.... -
Spores and pollen at DSDP Holes 36-330 and 71-511
Samples from Upper Jurassic and Lower Cretaceous sediments at Site 511 were analyzed for palynomorphs. Three palynological assemblages were identified: Upper Jurassic... -
