The southern Myanmar tin ore district is an important part of the well-known Southeast Asia belt (SATB), and hosts numerous economically primary tin-tungsten deposits. However, timing formation these deposits unclear due to scarcity robust age data. tectonic setting mineralization in this area also needs be further constrained. Most are typical hydrothermal quartz vein–type, with cassiterite wo...
The Qin-Hang Metallogenic Belt (QHMB), an important metallogenic belt in South China, hosts Cu and W–Sn polymetallic deposits. Tongshanling ore field the QHMB is characterized by coexistence of Cu- W-bearing deposits, which are related to granodiorite granite porphyry. This study examined whole-rock geochemistry, geochronology, Sr–Nd–Hf isotopes determine genetic relationship between diverse or...
our civilization is based on metals, among other life supports. the existing ore deposits are becoming rapidly depleted by almost exponentially increasing demand and production and major new ore discoveries are needed. mineral exploration is supported by modern tools and scientific ideas, but geological characteristics of orebodies and their rock associations have still to be visualized.the tim...

The Cheshmeh Zagh area is located on Khorasan Razavi Province, the southern parts of the Sabzevar zone, which is one of the most important metallogeny zones of Iran. Lithologically, the area includes a variety of Late Cretaceous volcanic rocks (dacite to basalt), intrusions (gabbro to synogranite), Oligo-Miocene sedimentary rocks, and Quaternary sediments. Alteration zones of propylitic, chlori...
Kishan lead-zinc deposit is one of the Malayer-Esfahan metallogenic belt deposits, located NW Arak, Markazi Province. The fluid inclusion microthermometry of the primary liquid-vapor bearing fluid inclusions trapped in the cogenetic quartz veins exhibited a homogenization temperature ranges from 140 and 272 °C (average 208.47 °C from 68 fluid inclusions), corresponding with the salinity of 10 t...
Abstract Rubidium (Rb) deposits mostly occur in the South China and Central Asia orogenic belts are often closely associated with highly differentiated granites. This study aimed to investigate a newly discovered giant Rb deposit at Gariatong Lhasa terrane Tibet. Detailed field studies logging data revealed that mineralization mainly occurrs monzogranite is related greisenization. LA‐ICP‐MS U‐P...
The gold mineralization located in the southern Eastern Desert of Egypt mostly occurs characteristic geologic and structural settings. gold-bearing quartz veins alteration zones are confined to ductile shear between highly deformed ophiolitic blocks, sheared metavolcanics, gabbro-diorite rocks. present study attempts integrate multisensor remotely sensed data, analysis, field investigation unra...
