The creationists are asking for equal time in science classrooms to teach that the Genesis stories are valid scientific interpretations of earth history. Equal time for creationists' interpretations are not likely to occur in secular universities and . . .

Rb-Sr isotopic data that produce "errorchrons" with large ± error values are commonly not published because more accurate dates calculated from isochrons are sought. An assumption is generally made that Sr is the only element that has moved out of the . . .

A megacrystal granodiorite, occurring in a pluton in the Monterey peninsula of California, is gradational south to quartz monzonite and then to tonalite and trondhjemite and southeast to granodiorite and then to tonalite. A primary magmatic origin for . . .

The present studies of granitoid rocks from the 1980s into the year 2001 are dominantly directed toward chemical analyses and experimental and theoretical petrology rather than the determination of textures and petrography as seen in thin sections. Va . . .

A horizontally-layered, biotite-rich diorite-gabbro in the Wanup pluton near Sudbury, Canada, is shown to be folded into a tight, nearly isoclinal anticline and then to evolve into a layered quartz monzonite-granodiorite body containing parallel bands . . .

Two of the many granitic plutons visited during the September 2-8, 1998, Eurogranites '98 field trip in northern Greece (Sideris et al., 1998) have particularly interesting textures or mineralogy. These granitic rocks are the megacrystal Kavala granod . . .

About 25 km south of Nakusp and 1 km east of Burton, British Columbia, Canada, is a stock whose western half is the Lower Caribou Creek megacrystal granodiorite and whose eastern half is the Goat Canyon-Halifax Creeks fine-grained quartz monzonite (Fi . . .

Alden Loomis studied the geology of the Fallen Leaf Lake 15-minute quadrangle in eastern California for his 1961 Ph.D. thesis. Many different granitic and relatively-mafic plutons (hornblende-biotite quartz diorite) occur in this area. These plutons e . . .

Various types of intergrowth textures occur in the Alvand plutonic complex, Hamadan, Iran. Intergrowth textures, such as myrmekite, perthite, micrographic (± granophyric), and tourmaline-microcline intergrowth, are most common in this suite. Perthite . . .
