Mafic xenoliths from S-type granitoids in the Lachlan Fold Belt (LFB), Australia, have radioactive heat productions which may exceed those of the host pluton. Mafic xenoliths from the LFB I-type granitoids contain low to moderate radioactive heat pro

The S-type granite suites comprising more than a quarter of the extensively developed granites in the Lachlan Fold Belt, Australia, contain monazite which may be related to the chemical weathering of the sedimentary source rocks. We report a process

The discovery in the late 1960s of the linear heat flow-heat production relationship was a major advance in the understanding of the thermal structure of continents. However, although heat flow provinces have now been defined in all continents except

The abundances of heat-producing elements increase and of rare-earth elements decrease upward in a 1 km vertical section through a pluton in the eastern Sierra Nevada batholith, California. This distribution results mainly from magmatic processes and

The zoned McMurry Meadows Pluton has been examined for REE and trace element variations in hornblende, sphene, apatite, allanite and zircon. Mineral separates (17), were analysed by INAA from four granitoids spanning the compositional range of the pl

About 150 samples of the plutonic rocks of the Raymond quadrangle were collected during geologic mapping. Of these, 137 were analyzed modally, 3 were analyzed chemically, and 4 were dated isotopically, 2 by the U-Pb method and 2 by the K-Ar method. I
