In the Urals, a wide range of well-preserved chimneys are found in VMS deposits, which are
associated with ultramafic (Atlantic type: Dergamysh), mafic (Cyprus type: Buribay), bimodal …

Bismuth occurs in a wide range of mineral deposit types and is usually regarded as a
deleterious by-product. Its classification as a critical raw material by the European …

The role of polymetallic melts in scavenging ore components has recently been highlighted
in the context of fluid-poor metamorphosed ore deposits. In contrast, the role of polymetallic …

The Yangzhaiyu gold deposit is one of numerous lode gold deposits in the Xiaoqinling
district, southern margin of the North China Craton. Gold mineralization is hosted in …

Several small pyrite±baryte±iron-oxide orebodies (Buca della Vena, Canale della Radice,
Fornovolasco, Monte Arsiccio and Pollone) are hosted in the metamorphic rocks of the …

Despite the close association between tellurium (Te) and gold (Au) in many epithermal,
orogenic, and intrusion-related hydrothermal ore deposits, the hydrothermal chemistry of Te …

Focussed ion beam–scanning electron microscopy (FIB–SEM) is a relatively new analytical
tool that has been little applied to problems of ore genesis. The technique enables high …

Abstract “Invisible gold” refers to gold (Au) occurring either within the lattice of a host sulfide
or as discrete nanoparticles (NPs,< 100 nm diameter) within a host that are only observable …

Abstract The Mesozoic Yangzhaiyu lode gold deposit is situated in the southern edge of the
North China craton. Gold mineralization is hosted in Archean amphibolite facies …

In hydrothermal ores, gold is commonly hosted by sulfide minerals due to its affinity for
reduced sulfur. In contrast, the occurrence of gold in oxide minerals remains poorly …
