(Table 1) Mineralogy at DSDP Leg 79 Holes

Four sites in the region of the Mazagan Plateau off northwest Africa were drilled during Leg 79 of the Deep Sea Drilling Project. Bulk mineralogy and clay mineralogy were analyzed from the Cenozoic sediments recovered from the four sites.

(Table 1) Abundance of radiolarians in the surface layer of bottom sediments from the Peru-Chile trench and shelf

Two radiolarian assemblages are distinguished: an equatorial sub-assemblage of the tropical assemblage in the East Pacific Ocean, which differs somewhat from association of radiolarians in the western part of the ocean, and an assemblage close to transitional one between the tropical and the boreal. The latter is characterized by presence of considerable number of species typical for cold-water regions. Some criteria are presented for distinguishing radiolarian associations in nearshore regions from similar associations in regions of the open ocean.

Major and trace elements and minerals at DSDP Hole 79-544A

Fifty m of basement rocks underlying 185 m of Neogene and Mesozoic sediments were drilled seaward of the Mazagan Slope about 100 km west of Casablanca during Leg 79. These rocks are metagranites with mylonitic textures consisting dominantly of quartz, plagioclase, and potassium feldspar. Chemically, they are strongly peraluminous. This along with the absence of hornblende suggest that these rocks are similar to the S-type granites. Petrographic and chemical data suggest the possible existence of a former weathering surface on top of the Mazagan metagranite.
