HeterogenousRock
type: Class
subclass of: SedimentaryRock
comment: A heterogeneous or conglomerate is a rock consisting of individual stones that have become cemented together. Conglomerates are sedimentary rocks consisting of rounded fragments and are thus differentiated from breccias, which consist of angular clasts.[1] Both conglomerates and breccias are characterized by clasts larger than sand (>2 mm). [Wikipedia]

MetamorphicRock
type: Class
subclass of: Rock
subclass of: Restriction
  all values from: Metamorphic
  on property: hasGenesis
comment: One of the major groups of rock that makes up the crust of the Earth; consists of pre-existing rock mass in which new minerals or textures are formed at higher temperatures and greater pressures than those present on the Earth's surface [wicktionary]

Melange
type: Class
subclass of: Rock
comment: A mélange is a large scale breccia, a mappable body of rock characterized by a lack of continuous bedding and the inclusion of fragments of rock of all sizes, contained in a fine-grained deformed matrix. The mélange typically consists of a jumble of large blocks of varied lithologies of altered oceanic crustal material and blocks of continental slope sediments in a sheared mudstone matrix. Some larger blocks of rock may be as much as 1 km across. [Wikipedia]

Meteorite
type: Class
subclass of: Meteor
comment: Meteoric substances are rocks that have composition significantly different from earth rocks. Meteorites have traditionally been divided into three broad categories: stony meteorites are rocks, mainly composed of silicate minerals; iron meteorites are largely composed of metallic iron-nickel; and, stony-iron meteorites contain large amounts of both metallic and rocky material. [Wikipedia]

Molasse
type: Class
subclass of: Sedimentary
comment: Molasse refers to the sandstones, shales and conglomerates formed as terrestrial or shallow marine deposits in front of rising mountain chains deposited in a foreland basin, especially on top of flysch, for example that left from the rising Alps, or erosion in the Himalaya. These deposits are typically the non-marine alluvial and fluvial sediments of lowlands, as compared to deep-water flysch sediments. Sedimentation stops once the orogeny stops, or once the mountains have eroded flat. [Wikipedia]

Regolith
type: Class
subclass of: Mixture
disjoint with: Rock
comment: Regolith (Greek: "blanket rock") is a layer of loose, heterogeneous material covering solid rock (bedrock). It includes dust, soil, broken rock, and other related materials [Wikipedia]

Rock
type: Class
subclass of: Mixture
subclass of: SolidSubstance
comment: Rock is a naturally occurring solid aggregate of minerals and/or mineraloids. In general rocks are of three types, namely, igneous, sedimentary, and metamorphic. [Wikipedia]

SedimentaryRock
type: Class
subclass of: Rock
subclass of: Restriction
  all values from: Sedimentary
  on property: hasGenesis
comment: One of the major groups of rock that makes up the crust of the Earth; formed by the deposition of either the weathered remains of other rocks, the results of biological activity, or precipitation from solution [wicktionary]

Fossil
type: Class
subclass of: SubstanceForm
comment: Fossils are the preserved remains or traces of animals, plants, and other organisms from the remote past. Fossils vary in size from microscopic, such as single bacterial cells [2] only one micrometer in diameter, to gigantic (macroscopic), such as dinosaurs and trees many meters long and weighing many tons. [Wikipedia]

Macrofossil
type: Class
subclass of: Fossil
comment: Macrofossils are preserved organic remains large enough to be visible without a microscope. [Wikipedia]

Microfossil
type: Class
subclass of: Fossil
comment: Fossils which are of microscopic size such as bacteria. [Wikipedia]
