two types of mineralization including porphyry copper and epithermal gold mineralization have occurred in relation with an intermediate volcano-plutonic complex in masjeddaghi area. different alterations including silica, advanced argillic, intermediate argillic and propylitic have been distinguished in relation with epithermal mineralization, which have a zonal pattern. elemental mass gains an...

the method of weights of evidence is one of the most important data driven methods for mineral potential mapping in gis. in this method, considering the characteristics of known mineralized locations, we can prospect new mineralized areas. in this research work, the method of weights of evidence has been used for hydrothermal gold potential mapping in torbat-e-heydarieh area, east of iran. as a...

Pucheng district is a part of the Wuyi Mountain polymetallic metallogenic belt, which constituted by Archean-Proterozoic metamorphic basements and Mesozoic volcanic-sedimentary covers. Uranium deposits are formed as volcanic-hosted structural controls. In this study, hybrid data-driven methods logistic regression (LR) weights evidence (WofE) were applied for mineral potential mapping uranium in...

the kuh shah prospecting area is located in tertiary volcano-plutonic belt of the lut block. more than seventeen subvolcanic intermediate to acidic intrusive rocks, diorite to syenite in composition, were identified in the study area. the intrusions are related to hydrothermal alteration zones and contain argillic, propylitic, advanced argillic, silicified, quartz-sericite-pyrite, gossan and hy...

The Nii Zn-Pb-Ag-Ba prospect is located in the headwaters of the Noosegolch River valley, approximately 23 kilometms north-east of Hagensborg in west-central British Columbia (Figure 1). The area lies within the Stikine Termne of the Coast Belt and is mostly underlain by various packages of matic to felsic volcanic, volcaniclastic and sedimentruy m&s @gore 1). Many of these packages are of unce...

Identification of geochemical anomalies is a significant step during regional geochemical exploration. In this matter, new techniques have been developed based on deep learning networks. These simple-structure-networks act like our brains on processing the data by simulating deep layers of thinking. In this paper, a hybrid compositional-deep learning technique was applied to identify the anomal...

Osmium isotope compositions and concentrations of Re, platinum group elements (PGE), and Au were determined for host peridotites (serpentinites and harzburgites) and hydrothermally altered ultramafic wall rocks associated with Mother Lode-type hydrothermal gold-quartz vein mineralization in the Alleghany district, California. The host peridotites have Os isotope compositions and Re, PGE, and Au...

The definition of pre-Messinian source rocks in the eastern Mediterranean is paramount importance for hydrocarbon exploration because ability salt to act as a high-quality seal rock. This research evaluates organic geochemical features Upper Miocene (Tortonian—Messinian) sedimentary succession onshore Crete Island, Greece. study employs original (Messinian, Agios Myron Fm) and published (Torton...
