The fast mineral exploration system with remote sensing is a brand new exploration system of recognition, identification, analysis and prediction. It takes metallogenic materials as the detection targets, uses the spectrum measuring technique as detection means and takes the spatial and temporal sequence of mineralization and alteration information as an evaluation basis. It develops and improv...

neyshabour turquoise mine is located in northwest of neyshabour, southern quchan volcanic belt. eocene andesite and dacite forming as lava and pyroclastic rocks cover most of the area. subvolcanic diorite to syenite porphyry (granitoids of magnetite series) intruded the volcanic rocks. both volcanic and subvolcanic rocks are highly altered. four types of alteration are recognized including: sil...

tertiary intrusive granitoids within the lut block in the khorasan razavi and south khorasan provinces are mainly sub-volcanic with porphyry texture and their composition varies from granite to diorite but monzonite is dominant. with the exception of hired, these are classified as belonging to the magnetite-series of i-type granitoids. chemically, these rocks are meta-aluminous. those with mine...

Abstract Filo del Sol is a composite porphyry-epithermal deposit, straddling the frontier between Argentina and Chile at latitude 28°29′ S, that has attracted great deal of recent attention because several drill intersections in excess 1 km long with unusually high Cu, Au, Ag grades. The deposit part 8.5-km-long, N- to NE-trending alignment porphyry high-sulfidation epithermal centers, which, t...

This review paper aims to integrate geological, tectonic and metallogenetic data, including new propose a regional model for the gold (and base metal) mineralization in south Amazonian Craton support mineral exploration concerning magmatic–hydrothermal deposits. The Proterozoic evolution of comprises accretion terrains Archean Carajás Mineral Province. In Tapajós Juruena provinces, located at p...

The mid-Proterozoic (ca. 1850–850 Ma) is a peculiar period of Earth history in many respects: ophiolites and passive margins this age are rare, whereas anorthosite A-type granite suites abundant; metamorphic rocks typically record high thermobaric (temperature/pressure) ratios, ultrahigh pressure (UHP) rare; the abundance economic mineral deposits features rare porphyry Cu-Au abundant Ni-Cu Fe-...
