The crystal chemistry of anorthite with low content of albite (An92.0 Ab3.4), part of a rapidly cooled anorthite megacryst occurring in 1940 ejecta from Miyake-jima volcano, Japan, has been investigated using a single-crystal X-ray diffractometer and

Zircon from granitic rocks, Japan is classified into two major types; based on the minor element content determined by electron microprobe, a heavy rare earth element (HREE)-U-Thpoor (Type I) and a HREE-U-Th-rich (Type 2). Zircons characteristically

Euhedral dissakisites from Trimouns dolomite mine, France, is compositionally zoned. Back-scattered electron (BSE) images reveal that each of the described dissakisite crystals has three distinct compositional zones: normal zoned core (Mg-rich), osci

We have investigated allanite phenocrysts and the apatite and zircon inclusions they contain from three localities: (1) SK100 ash beds, Niigata, Japan, (2) the youngest Toba Tuff (YTT), Sumatra, Indonesia, and (3) the Bishop Tuff (BST) in eastern Cal

The isotopic compositions of Sr and Nd were analyzed for sixteen samples of allanite-(Ce) from Mesozoic–Cenozoic granitic rocks in Japan (11 samples of an Mn-rich type, and five samples of an Mn-poor type). The Mn-rich allanite-(Ce) crystals have a
