Genesis of nelsonite from the Damiao Fe-Ti-P deposit, Hebei Province, China: Evidence from apatite
河北大庙Fe-Ti-P矿床中铁钛磷灰岩的成因: 来自磷灰石的证据

Nelsonites,which consist essentially of Fe-Ti oxides and apatite,are spatially and temporally associated with Proterozoic massif-type anorthosites,and have been interpreted as either cumulate rocks or the products of immiscible melts.The Damiao anorthosite massif in Hebei Province in China,contains numerous disseminated and vein-type Fe-Ti oxide and apatite orebodies.The disseminated ores are hosted in homogeneous silicate rocks,whereas the vein-like bodies occur as veins,lenses and rhythmic layers of massi...
