The Bohai Bay Basin basement is mainly composed of Archean granitoid gneisses with minor supracrustal rocks and the largest basin in Eastern Block North China Craton. Due to a cover Mesozoic Cenozoic strata, little known about age crustal evolution this basement. In study we report new zircon SHRIMP LA-ICP-MS U-Pb Lu-Hf isotope data for drill core samples, including TTGs (granodiorite, tonalite...

The Xinchenggou area is located in the northeast part of eastern segment Xingmeng orogenic belt (EXOB), NE China and has been demonstrated to be a promising exploration target for epithermal deposits. Although previous studies have shown that syenogranite monzogranite occurring are forming mineralization, petrogenesis geodynamic settings which these granites were emplaced still unclear. To addr...

Abstract Cretaceous igneous rocks in SW Borneo are significant for investigating the Paleo-Pacific subduction and regional correlation. This paper presents new zircon ages Sr–Nd–Pb–Hf–O isotopic whole-rock geochemical data granitoids Schwaner Mountains. These granitoid samples yield formation of 92–80 Ma can be geochemically subdivided into Group 1 biotite granite granodiorite 2 monzogranite. h...

Kahang Cu Porphyry deposit is situated in the central part of a major Iranian magmatic belt, Urumieh-Dokhtar, in central Iran.There are several sub-volcanic stocks (e.g., porphyric granitoids rocks, quartz monzonite, diorite and monzodiorite-monzogranite)within Eocene volcanic and pyroclastic rocks consisting of basaltic, trachy-andesite and dacitic rocks. Hydrothermal alterations at the Kahang...

The Longquanzhan deposit is one of the largest gold deposits in Yi-Shu fault zone (central section Tan-Lu zone) Shandong Province, China. It an altered-rock type which ore bodies mainly occur at contact between overlying Cretaceous rocks and underlying Neoarchean gneissic monzogranite. Shi et al. reported that this formed 96 ± 2 Ma using pyrite Rb–Sr dating method represents a new mineralizatio...

The current study presents the integration between field observations and remotely sensed data for detection extraction of geological structural features using Sentinel-2A Aster DEM images. area under investigation is represented by Neoproterozoic East African Orogeny encompassing a part Arabian Nubian Shield. All rock units studied belong to Late Cryogenian-Ediacaran periods that are divided i...

This paper present new U–Pb geochronological data (LA-ICP MS on zircon) of granitoids from the Moroccan Meseta Variscan belt. Zircons Oulad Ouaslam granodiorite in Jebilet massif Western highlight a peak magmatic activity at 335.2 ± 0.8 Ma. In Eastern Meseta, ages obtained several facies High Moulouya complex restrained its to early Visean: 339.6 1.9 Ma for Perdreaux granite, 337 1.6 calc-alkal...

The Ailaoshan orogenic belt is one of the most significant belts in southeastern margin Qinghai–Tibet Plateau. widely developed magmatic rocks this preserve multi-stage tectonic evolution records South China Plate. As an important response to Rodinia breakup event, study Neoproterozoic area great significance for reconstructing process and Petrology, geochemistry, zircon U-Pb, Lu-Hf isotopes Da...

Abstract High-silica (>70 wt% SiO2) magmas are usually believed to form via shallow crustal–level fractional crystallization of intermediate magmas. However, the broad applicability this model is controversial, because required crystal-melt separation processes have rarely been documented globally up now. The ca. 50 Ma Nyemo composite pluton Gangdese batholith belt in southern Tibet, whi...
