conglomerate Coarse grained (rudaceous) rock with rounded clasts that are greater than 2mm in size. Conglomerates may be termed ‘intraformational’ if formed of local, recently deposited clasts, or ‘extraformational’ if the clasts are derived from outside the area of deposition. The term ‘polygenetic’ is used to describe a conglomerate rock that has been produced under a variety of conditions or processes.

conglomerate, in geology, sedimentary rock composed largely of pebbles or other rounded particles whose diameter is larger than 2 mm (.08 in.). Essentially a cemented gravel, conglomerates are formed along beaches, as glacial drift, and in river deposits. Conglomerates formed of angular shaped pebbles are called breccias.

CONGLOMERATE

A corporation operating in several different and unrelated enterprises, such as the movie industry, baking, and oil refining.

A conglomerate merger is one that brings together two firms with totally different product lines, economic relationships, and functions. Such a merger may violate antitrust acts inasmuch as it may have an adverse effect on competition.
