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...

The Santa Lúcia copper-gold deposit lies in the southeastern portion of Carajás Mineral Province, along NW-SE splays Fault. is hosted by a rhyolitic subvolcanic rock, which crosscut pegmatite intrusions. paragenetic evolution at encompasses an early stage chlorite alteration, followed potassic alteration with microcline, greisenization (quartz-muscovite-tourmaline), ore precipitation, and late ...

Hyperspectral cathodoluminescence (CL), geochemical, and geochronological characterization of a series apatite-bearing samples from within around the Ernest Henry IOCG deposit, NW Queensland, Australia, have revealed complex mineral parageneses spectrum U-Pb ages that point to effects multiple geological processes. No two are identical, either in geochemistry or texture, despite their relative ...

Zircon geochemistry and geochronology are powerful tools in the study of multistage cratonic settings, yielding information on ages distinguishing terranes. The Carajás Mineral Province (CMP) SE Amazonian Craton is renowned for its complex tectonic evolution notable mineral deposits endowment, such as giant iron-oxide-copper-gold (IOCG)-type Sossego Salobo. Tectonic, magmatic, metamorphic, hydr...
