Conodont Color Alteration (CAI) as an Aid to Structural Interpretation in the Black Pine Mountains, Idaho

By J. Fred Smith, Jr. and Bruce R. Wardlaw

Thumbnail of and link to report PDF (292 KB)Abstract

The Black Pine Mountains, southeastern Cassia County, Idaho, consist of southern and northern blocks separated by a northeast-trending, high-angle fault. Differences in conodont color alteration values distinguish the two blocks. The southern block has significantly higher organic maturation levels than the northern block and is interpreted to have been thrust northeastward adjacent to the northern block.
