Geology and ground-water resources of puerto rico

Puerto Rico, the easternmost and smallest of the Greater Antilles, has an axis of deformed and metamorphosed volcanic rocks of Upper Cretaceous age, intruded by dioritic rocks during the Antillean revolution. The hard-rock core is flanked on the north and south by limestones and clastic rocks of late Oligocene and early Miocene age, which have been gently arched and uplifted. Similar rocks were de

The zinc content of plants on the friedensville zinc slime ponds in relation to biogeo-chemical prospecting

The zinc content of thirty different kinds of plants growing on slime ponds containing on the average 12.5 per cent zinc were determined by the dithizone method. The zinc content ranged from 39 p.p.m. in the fruit of the false Solomon's seal (Smilacina racemosa) to 5,400 in the horsetail (Equiseteum arvense). This latter plant varied considerably in zinc at different places on the slime ponds. The

The sangdong tungsten deposit, southern Korea

The Sangdong deposit consists of metamorphosed lenticular beds in a sequence of gently dipping argillaceous sedimentary rocks. It is believed that scheelite mineralization was simultaneous with metamorphism, followed by deposition of wolframite during a later hydrothermal phase. The reserve of ore is estimated to be 3,000,000 tons, containing 51,000 tons of WO (sub 3.)

Radioactivity of the rocks of the batholith of southern California

Determination of radioactivity has been made on 43 rocks, carefully selected from the different mapped units of the complex Cretaceous batholith of Southern California; they range from gabbro to granite. The activity of the gabbro averages about 0.3 alphas/mg./hr., that of the tonalites, 0.8, the granodiorite 1.3, and the granites over 2.0. The activity of the average rock of the batholith is abou

Petrology and structure of the Moa Chromite district, Oriente Province, Cuba

Chromite deposits In the Moa district, on the north coast of Oriente Province, Cuba, form one facies of the ultramafic complex in which they occur. Two planar structures, one a compositional layering due to variations in the relative proportions of olivine, pyroxene, plagioclase feldspar, and chromite, and the other a foliation caused by the orientation of pyroxene crystals in peridotite, are in g
