- 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,
Kennisbergs 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.
