As Lower Coralline Limestone is a very hard rock, it is very difficult to erode. Because of these characteristics, it has its own set of landforms. In the areas where this type of rock is found, there is the production of vertical sheer cliffs. Examples are the cliffs in the Western side of the Maltese Islands like Ghar Lapsi and Dwejra.

These deposits are nonmarine except in southeastern Arizona, where prominent gray marine limestone (Mural Limestone) forms the middle of the Bisbee Group. Sandstones are typically mediumbedded, drab brown, lithicfeldspathic arenites.

The limestone of the Maltese Islands was formed in shallow waters about 22. million years ago. Malta's megalithic temples are all made out of limestone, dating back to 6000. years, making them the oldest free standing structures in the world. A normal sized 'kantun' can weigh up to 75kg.

There are about 40 limestone and dolomite quarries in southwestern Ontario but only a few of them have produced significant mineral specimens. All of them have some vugs of varying sizes with simple calcite or other crystals but only a few have fine, larger, well crystallized minerals such as fluorite, celestine, sphalerite, calcite, marcasite, gypsum, pyrite and pyrite ps pyrrhotite.

The geology of the Maltese islands comprises a succession of Tertiary limestones and marls from the top of Oligocène to the Miocene, with scarce Quaternary deposits (Fig. 1). Basically the succession consists of a central core of clays and marls, the Blue Clay (SerravallianTortonian) and the Globigerina Limestone formations stacked

· The limestone is mainly deposited in calm, warm marine water at shallow depths where organism are capable of generating calcium carbonate shells and skeleton. These organism when die accumulate in the area to form limestone deposits. The waste product of these organism also contribute to sediment mass which in turn when lithifies produces limestone.

Within the predominantly limestone rock there are some alluvial deposits and conglomerates of ferruginous and siliceous material. Note: This page is still in preparation. It lacks a number of images and most of the text. It is limited to Palaeontology (fossils). It shows images mainly of tertiary and of quaternary fossils from Malta.
