Diabase An intrusive mafic rock forming dykes or sills

Diabase or dolerite or microgabbro is a mafic, holocrystalline, subvolcanic rock equivalent to volcanic basalt or plutonic gabbro. Diabase dikes and sills are typically shallow intrusive bodies and often exhibit fine grained to aphanitic chilled margins which may contain tachylite. Diabase is the preferred name in North America, yet dolerite is the preferred name in most of the rest of the world, where sometimes the name diabase is applied to altered dolerites and basalts. Many petrologists prefer the name microgabbro to avoid this confusion.

Island Any piece of sub-continental land that is surrounded by water

An island or isle is any piece of sub-continental land that is surrounded by water. Very small islands such as emergent land features on atolls can be called islets, skerries, cays or keys. An island in a river or a lake island may be called an eyot or ait, and a small island off the coast may be called a holm. A grouping of geographically or geologically related islands is called an archipelago, such as the Philippines.

Hectare Metric unit of area

The hectare is an SI accepted metric system unit of area equal to a square with 100-metre sides, or 10,000 m2, and is primarily used in the measurement of land. There are 100 hectares in one square kilometre. An acre is about 0.405 hectare and one hectare contains about 2.47 acres.

Fauna

Recorded breeding seabird and wader species are the little penguin (400 pairs), short-tailed shearwater (6000 pairs), Pacific gull and sooty oystercatcher. [1]

Seabird Birds that have adapted to life within the marine environment

Seabirds are birds that are adapted to life within the marine environment. While seabirds vary greatly in lifestyle, behaviour and physiology, they often exhibit striking convergent evolution, as the same environmental problems and feeding niches have resulted in similar adaptations. The first seabirds evolved in the Cretaceous period, and modern seabird families emerged in the Paleogene.

Wader

Waders are birds commonly found along shorelines and mudflats that wade in order to forage for food in the mud or sand. They are called shorebirds in North America, where the term "wader" is used to refer to long-legged wading birds such as storks and herons. Waders are members of the order Charadriiformes, which includes gulls, auks and their allies.

Little penguin smallest penguin species

The little penguin is the smallest species of penguin. It grows to an average of 33 cm (13 in) in height and 43 cm (17 in) in length, though specific measurements vary by subspecies. It is found on the coastlines of southern Australia and New Zealand, with possible records from Chile. In Australia, they are often called fairy penguins because of their small size. In New Zealand, they are more commonly known as little blue penguins or blue penguins owing to their slate-blue plumage; they are also known by their Māori name: kororā.

Geographic coordinate system Coordinate system

A geographic coordinate system is a coordinate system that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are often chosen such that one of the numbers represents a vertical position and two or three of the numbers represent a horizontal position; alternatively, a geographic position may be expressed in a combined three-dimensional Cartesian vector. A common choice of coordinates is latitude, longitude and elevation. To specify a location on a plane requires a map projection.
