In this paper new geochemical, geochronological and isotopic Lu–Hf data from the Siempre Amigos Hills (SA), western Tandilia, Argentina, is presented. Outcrops in small area include representative lithologies of basement Río de la Plata craton (RPC) known as Tandilia Terrane. The geochemical characterize a heterogeneous Paleoproterozoic crust with similar U–Pb SIMS magmatic age (~2.1 Ga) repres...

the asinawa iron ore is located about 3km to the southeast of penjween town, sulaimaniya governorate, kurdistan region, northeastern iraq near the iraq-iran border. the exposed iron ore deposit is about 60 and 400m wide and long respectively. the present study is the re-study of the geology and geochemistry of the asnawan iron ore deposit  and concluded that the country rocks are consist of hor...

The Northern Dabie Complex in east central China lies between the Sino–Korean plate to the north and the Yangtze plate to the south. The Northern Dabie Complex has been variously proposed to represent a Paleozoic magmatic arc on the Sino–Korean plate, an exhumed piece of subducted Yangtze plate crust, or crust produced almost entirely by Cretaceous extension-related magmatism. Trace element com...

The isotope geochronology of isochronously deposited Cambrian strata from different tectonostratigraphic zones of the Himalaya confirms new stratigraphic, sedimentological, and faunal evidence indicating that the Himalaya was a single continental margin prior to collision of India with Asia. Lesser, Greater, and Tethyan Himalaya represent proximal to distal parts of a passive continental margin...

The selected peridotite samples come from the Josephine ophiolite, emplaced 157 My ago and now part of the western Jurassic belt of the Klamath Mountains in Northern California and Southwest Oregon [1]. The ophiolite is partly dismembered but presents a complete ophiolitic section from mantle peridotites in the lower part (our samples) to pillow lavas at the top. The Josephine peridotite extend...

Introduction: On Mars, the geomorphology of numerous surface features has been attributed to the interaction of magmatic and impact heat sources with an H 2 O-rich Martian crust/megaregolith [1-3]. In addition , geochemical analyses of soil at the Pathfinder and Viking landing sites indicate high concentrations of SO 3 and Cl [4-6], consistent with interaction between a basaltic protolith and f...
