"Lineations within the Tri-State mining district are classified as megalineaments, lineaments and linears, based on length. One megalineament, 120 lineaments and 205 linears are identified on the LANDSAT imagery. In order of importance a dominant northeast set, northwest set, north-south set and east-west set are recognized. These range from 0.8 miles (1.3 km) to 68 miles (109.4 km) in length.
Major lineation trends spatially relate with trends of mined areas In the Picher field both northeast and northwest lineations generally parallel mined areas. In the Galena field ore and lineations trend northeast while in the Joplin and Duenweg-Webb City-Oronogo field the lineations and ore trends are northwest. The Seneca graben and Pineville fault relate to well expressed lineaments. Field checks indicate joint sets have similar trends to mapped lineaments.
Lineaments are most numerous in massive, more competent rock units such as the Boone Formation. This is also the most productive stratigraphic formation for ore deposits. Lineations may have acted as passageways for mineralizing solutions.
The lineation pattern of the district is similar to the regmatic shear pattern of the earth. External (tidal) and internal (tectonic) forces may develop the lineations. Pattern variations may result from local internal stresses. Some northeasterly and northwesterly lineations are due to a compressive stress, while the Seneca, Miami and some normal faults, all of northeast trend, relate to tensional stresses of opposite direction.
Areas of southwestern Missouri underlain by competent units and with expressed lineaments,and extension of mined zones with lineament expression are possible favorable areas for mineral exploration"--Abstract, page ii.
