The Bouse Hills are located in west-central Arizona (Fig. 1) and are within the Basin and Range physiographic province of the Southwest. The Bouse Hills consist of four rock assemblages (Fig. 2), as follows: (1) Proterozoic crystalline rocks, (2) moderately to steeply tilted Oligocene(?) to lower Miocene volcanic and sedimentary rocks, (3) a Miocene pluton and related dikes, and (4) flat-lying to gently tilted Miocene volcanic and minor sedimentary rocks. Assemblages (1) and (2) were tilted by early Miocene rotational normal faulting that was widespread in the Basin and Range province (Spencer and Reynolds, 1989). In the Bouse Hills, tilting was probably related to movement on the Plomosa detachment fault which projects beneath the Bouse Hills from the west (Scarborough and Meader, 1989). Manganese and barite mineral deposits are mineralogically distinct, and fluid-inclusion data indicate that they were derived from aqueous fluids with different salinities. These deposits are confined to the Miocene volcanic and sedimentary rocks. This report includes a geologic map of the Bouse Hills at a scale of 1:24,000 (plate 1), descriptions of rock units (Appendix 1), and a stratigraphic correlation diagram (Fig. 3). Also included are descriptions of mineral deposits (Appendix 2) and a geologic map of some small hills northwest of the Bouse Hills (Fig. 4). ( 21 pages)
