WHAT KIND OF TEXTURE WILL A CONGLOMERATE ROCK HAVE?
Conglomerateis a sedimentary rock created from rounded gravel and also boulder sizedclasts cemented together in a matrix. The rounding of the clasts shows that they have been transported somedistance from your original resource (e.g. By a river or glacier), or the they have actually resided in a high energy environmentfor some time (e.g. Top top a beach subject to wave action). The cement that binds the clasts is generally one that eithercalcite, silica or steel oxide. The matrix deserve to consist exclusively of the cementing material, however may likewise containsand and also / or silt size clasts cemented together among the coarser clasts. Conglomerates deserve to be additional dividedaccording to:
Class - conglomerate deserve to be separated into two broad classes:Clast supported - where the clasts touch each other and also the matrix fills the voids; andMatrix supported - wherein the clasts are not in contact and also the matrix surrounds each clast;
Sorting - a conglomerate comprising a mixture of clast size is poorly sorted, when one making up mostly clastsof the very same size is fine sorted;
Lithology - a conglomerate where the clasts represent an ext than one rock form is termed polymictic (or petromictic),while one where the clasts are of a single rock form are monomictic (or oligomictic).
Texture -clastic (coarse-grained).Grain dimension - > 2mm;clasts easily visible come the naked eye, should be identifiable.Hardness - variable, soft come hard, dependent on clast composition and also strength of cement.Colour - variable, dependence on clast and matrix composition.Clasts - variable, but generally more tough rock varieties and / orminerals dominate.Other functions - clasts usually smooth to touch, matrix variable.Uses - as dimension rock for decoration of walls and also floors; if difficult can be supplied as aggregate, to fill etc. Inthe construction and roading industries.New Zealand incidents - sporadic event throughout the country, often exposed on coastlines (Hawkes Bay(Cape Kidnappers), Wairarapa), Canterbury Plains; generally uncovered interbedded withsandstone andmudstone.
