Other metalliferous industries took its place, as did a greater emphasis on engineering products.

A typical source of such aggregates is metalliferous mine waste.

The Caledonian orogeny was a period of intense metalliferous mineralisation.

Henwood soon took an active interest in the working of mines and in the metalliferous deposits.

Cases were unloaded, the metalliferous earths hosed from the bins into the holds.

Many areas, mainly on Grand Terre have some very high concentrations of metalliferous rocks.

This was not a metalliferous star; no prospector had ever bothered to check out those lumps of rock for anything of value; none ever would.

Drainage patterns are very well developed in the upland areas of northern and western Britain which form the most favourable areas for metalliferous mineral exploration.
