Porphyry deposits are large, low-grade metal ore bodies that are formed from hydrothermal
fluids derived from an underlying magma reservoir. They are important as major sources of …

Abstract Magnetite (Fe 3 O 4) is a well-recognized petrogenetic indicator and is a common
accessory mineral in many ore deposits and their host rocks. Recent years have seen an …

Many workers accept a metamorphic model for orogenic gold ore formation, where a gold-
bearing aqueous-carbonic fluid is an inherent product of devolatilization across the …

The timing and mechanism of ore precipitation in porphyry copper systems are hot topics
and remain controversial. The large Miocene collision-related Zhunuo porphyry Cu deposit …

The term orogenic gold deposits has been widely accepted, but there has been continuing
debate on their genesis. Early syn-sedimentary or syn-volcanic models and hydrothermal …

Much of the world's economic copper resources are hosted in porphyry copper deposits
(PCDs), shallow level magmatic intrusions associated mostly with thick (> 45 km) magmatic …

A fundamental question in the study of magmatic-hydrothermal ore deposits is whether the
mineralization potential of intrusions was already predetermined by the metal content of the …

The chemical composition, textures and mineral associations of pyrite provide key
information that help elucidate the evolution of hydrothermal systems. However, linking the …

Nanofibres can be fabricated by various methods and perhaps electrospinning is the most
facile route. In past years, electrospinning has been used as a synthesis technique and the …

Nanofibers obtained using electrospinning technique are being used since ages especially
in fields of textile industry, sensors, filters, protective clothing and tissue engineering. Their …
