Rocks of the Proterozoic gabbro—diorite—tonalite—trondhjemite suite southwest Finland were analyzed for major elements, REE, Rb, Sr, Ba, U, Th, and isotopic composition Sr O. Petrographic continuity from hornblendite through hornblende gabbro, hornblende—biotite diorite, tonalite trondhjemite is reflected in regular variation trace elements samples ranging 42 to 74 per cent SiO2. The calc alkaline—trondhjemitic distinguished ‘normal’ calc-alkaline suites by increase Na2O decrease K2O REE...
Initial 87Sr/ 86 Sr was determined for samples of Mesozoic granitic rocks in the vicinity Garlock fault zone California. These data along with similar from Sierra Nevada and San Andreas system permit a reconstruction basement offset by Cenozoic lateral faulting both systems. The location line initial = 0.7060 can be related to edge Precambrian continental crust western United States. Our model explains present configuration as result two stages rifting that occurred about 1,250 800 m.y. ago,...
Analyses of particle size distributions indicate that clay minerals and other diagenetic metamorphic commonly undergo recrystallization by Ostwald ripening. The shapes their can yield the rate law for this process. One consequence ripening is a record process preserved in various sizes. Therefore, one determine detailed geologic history clays recrystallized separating, from single sample, sizes independent chemical, structural, isotopic analyses.

This paper presents new radiometric data that permit some qualified statements to be made on the depositional history of Belt sedimentary rocks. The period deposition rocks Precambrian Series has been placed within a broad time interval, for they rest metamorphosed basement rock dated at ~ 1800 m.y. and are overlain by Middle Cambrian Flathead Quartzite (circa 530 m.y.). Prior geochronometric gathered during last decade indicate most older than 1100 m.y.K–Ar Rb–Sr techniques have applied...

Like the recently published data Deep Sea Drilling Project (DSDP) carbonates, at increases monotonically but not smoothly early Miocene to Pleistocene. The show intervals little or no change in 86/Sr, punctuated by sharp transitions lower values toward greater depths. correlate with observed solution disconformities caused...
