The Rocks

QUARTZITE

A massive (homogeneous and unlayered) siliceous rock, consisting of quartz crystals produced from quartz-rich sandstone when the sand grains and the silica that cements them together recrystallise. The crystals are milky white in colour, or orange because of the presence of iron oxides.

GRANITE

A grainy-textured plutonic rock formed by the crystallisation of magma deep within the earth and consisting essentially of quartz, potassium feldspars, plagioclase feldspars, and frequently micas.

SCHIST

Broadly speaking, any rock with a foliated (layered) structure, but the strict definition is metamorphic rock that has acquired a foliated structure through the effect of tectonic stresses (pressure). The micas are often aligned, the surfaces of the folia having a glossy or silky sheen.

 

TUFA

Volcanic tufa, or tuff, is a rock with a porous structure. Calcareous tufa, also known as travertine, is a form of limestone and is of sedimentary origin.

 

SERPENTINITE

A green, often dark green, metamorphic rock that is a constituent of ophiolites. It is also known as pot stone or soapstone and has long been used to make stoves and containers.

 

LIMESTONE

A sedimentary rock, like sandstone and gypsum, that is readily water-soluble (cf. karst), consisting mostly of calcium carbonate but also of magnesium carbonate. Where the rock has a significant proportion of clay (about 50%) it is known as marl.

 

GNEISS

A crystalline metamorphic rock characterised by dark-coloured layers (micas, amphiboles) alternating with light-coloured layers (quartz, feldspars). There are several different types.

CONGLOMERATE

A hard rock consisting of rounded or sub-rounded gravel and cobbles, cemented by limestone or silica.
