GEOLOGY OF THE NORTHEASTERN PART OF THE IDAHO BATHOLITH AND ADJACENT REGION IN MONTANA' CLAUDE M. LANGTON University of Chicago ABSTRACT The region is composed mainly of sediments of the Belt series and of gneisses and schists in the immediate vicinity of the Idaho batholith.

The structures become more. The region is composed mainly of sediments of the Belt series and of gneisses and schists in the immediate vicinity of the Idaho batholith. The structures become more complex as one approaches the batholith, and evidence is given for two periods of folding and faulting of which the later deformation occurred near the time of the batho-lithic by: Buy Petrology of the northeastern border zone of the Idaho batholith, Bitterroot Range, Montana, (Montana.

The batholith is Late Cretaceous in age and is emplaced immediately east of the Triassic Seven Devils volcanic arc. The Idaho Batholith is a granitic and granodioritic batholith of Cretaceous-Paleogene age that covers approximat Geology of the northeastern part of the Idaho batholith and adjacent region in Montana.

The ancient sedimentary formations of northern Idaho, the Idaho batholith in the central part of the state, the continental hot spot track and newly discovered meteorite impact crater of the volcanic Snake River Plain, and the Active faults of the Basin and Range province are all chapters in an exciting geologic story/5(38).

The Idaho batholith ecoregion is bordered on the north by the Northern Rockies, on the east by the Middle Rockies, on the south by the Snake River Plain, on the west by the Blue Mountains, and partially on the northwest by the Columbia Plateau.

It has been subdivided into eleven Level IV ecoregions in Idaho and Montana. Although geologic events that have been part of Idaho's development have gone on for at least 3 billion years, as evidenced by the oldest rocks in the state, most of the action leading to Idaho's magnificent landscape occurred only in the last million years, or so.

Similar in age and composition to the Sierra Nevada Batholith, the Idaho Batholith was fed by magma created during subduction along the west coast of North America.

The jagged peaks in the north part of the view are in the Eocene Sawtooth batholith. The more gentle peaks south of the prominent glacial lake (Alturas Lake) in center of view are cut from Cretaceous granodiorite of the Idaho batholith.

The major magnetic anomalies in the area east of the northern part of the Basin and Range province and east of the overthrust belts in southeastern Idaho and western Montana reflect lithologic contrasts in the Precambrian basement with prominent northeast and northwest trends.

Rafting down the Main Salmon River, which courses north and then west across northern Idaho, takes you by Precambrian metamorphics and the granites of the Idaho Batholith. Six to eight days later, your trip concludes as you float past what was once the edge of North America, and over former island arcs sutured onto the continent during the Mesozoic.
