Pegmatites are texturally complex igneous rocks marked by some combination of coarse but
variable crystal size, mineralogical zonation, prominent anisotropy of crystal orientations …

Abstract Cameron et al.(1949) devised the nomenclature and delineated the patterns of
internal zonation within granitic pegmatites that are in use today. Zonation in pegmatites is …

Rare-element granitic pegmatites are well recognized for the diversity and concentrations of
metal ores that they host. The supply of some of these elements is of concern, and the …

Igneous rocks with high Ta concentrations share a number of similarities such as high
Ta/Nb, low Ti, LREE and Zr concentrations and granitic compositions. These features can be …

A new scheme of nomenclature for the pyrochlore supergroup, approved by the CNMNC–
IMA, is based on the ions at the A, B and Y sites. What has been referred to until now as the …

Tantalum, an important metal for high-technology applications, is recovered from oxide
minerals that are present as minor constituents in rare-metal granites and granitic rare …

Abstract Despite Nb and Ta being considered as 'geochemical twins', most Ta mineral
deposits are associated with muscovite-bearing peraluminous granites and related …

The identification of a magmatic source for granite-associated rare metal (W, Nb, Ta and Sn)
mineralisation in metasediment-hosted quartz veins is often obscured by intense fluid–rock …

Abstract The Xiangdong W (-Sn) deposit is hosted in the Dengfuxian multiphase granites
(biotite, two-mica, and muscovite granites) within the Nanling Range metallogenic belt in …

Abstract The recently discovered Renli Tasingle bondNb deposit in northeastern Hunan
Province is the largest known pegmatite Tasingle bond Nb deposit in South China. Previous …
