Information @ a Glance

  • Trap rock is a form of plutonic igneous rock that tends to form polygonal vertical fractures, most typically hexagonal, but also four to eight sided.
  • Trap rock is the primary constituent of many ridges and other rock outcrops in the Hudson River valley, such as the Palisades, and southern New England.
  • Traprock - term widely used by quarry operators and their clients for basalt and coarser ("microphaneritic") rocks.
  • Basalt is an aphanitic igneous rock that, with a petrographic microscope, can be seen to consist largely of a dark colored pyroxene and a light to medium dark colored plagioclase feldspar with or without minor amounts of glass.
  • Traprock, granite and sandstone soils retain little moisture.
  • Trap rock is commercially quarried and crushed to provide hard bulk in composite materials that bond it together, such as concrete and macadam.
  • Slightly coarser old sheets of basalt, now partially altered but still dark in color, are extensively quarried, crushed, and sold as "traprock".
  • A special attention in study of traps is paid for methods of investigation of a magnetic field as well as direct study of magnetic parameters of trap rock samples such as natural remanent magnetization (In), magnetic perception, KennisbergŠs factor (Qn), declination (D), inclination (J).
  • Dresser Traprock is not friendly to jaw crushers or cone crushers used to bring the mined rock into marketable products. Its extreme hardness resists fragmentation and in turn, that means the crusher's parts directly exposed to the rock during the crushing process need to withstand repeated severe impacts.
  • Some soils derived from traprock have hard-setting surfaces.
  • In crushed aggregate form, trap rock's gray color dominates; as boulders, it displays subtle hues of gray, blue, red, pink and purple. As a result, the aesthetic value of trap rock in decorative applications applies equally to landscaping as well as ground cover.
  • The estimated U.S. output of aggregates sold or used in the first quarter of 2006 increased in eight of nine geographic divisions and remained unchanged in the ninth division. The largest increases were recorded in the New England (14.4 percent), the Mountain (10.9 percent), and the Middle Atlantic (10.8 percent) divisions, according to the report.
