  • This is a weathered sample of the rock used to make the monument Stonehenge in England.; This is a sample of Preseli Spotted Dolerite—a chemically altered igneous rock containing spots or clusters of plagioclase feldspar. It is a medium grained dark and heavy rock; harder than granite.; The bluestones at Stonehenge were placed there during the third phase of construction at Stonehenge around 2300 BC.; The majority of them are believed to have been brought from the Preseli Hills; about 250 miles away in Wales.

  • Gypsum. Polarized light micrograph of a thin section of gypsum. Gypsum is a chemical sedimentary rock, composed mainly of hydrated calcium sulphate. It may grow as a crystal aggregate (as here) or in giant tabular crystals up to 1 meter in length. Gypsum is used in plaster of Paris, in Portland cement and as a flux in pottery. The most compact form of gypsum is known as alabaster. Sample collected in Penfield, New York.  Object size: 40 mm.

  • SEM of a conodont tooth.  Acid etched from 500 million year old rock. Scientists are still unsure how these teeth were placed in most of the species.  Conodonts are extinct chordates resembling small eels maybe the size of the modern earthworm.  Classified in the class Conodonta. For many years, they were known only from tooth-like microfossils now called conodont elements, found in isolation. Knowledge about soft tissues remains relatively sparse. The animals are also called Conodontophora (conodont bearers) to avoid ambiguity.  This specimen was .5 mm wide and was collected in Ohio.

  • The quartz crystal optical wedge is a simple technique to aid in specimen identification by inducing a color gradient in a polarizing microscope. The wedge is made from a crystalline block of quartz cut into a wedge angle so that the optical axis of the quartz is oriented either parallel or perpendicular to the edge of the birefringent crystal. A typical quartz wedge is useful for measurements of petrographic specimens (rock and mineral thin sections) or other birefringent materials. The quartz wedge compensator is also employed for the determining the direction of anisotropy (crystalline fast and slow axes orientation) in birefringent specimens.

This process is very easy and takes place in a lime kiln. Lime can be made from sea shells, chalk, and many types of rock - including marble.

  • .Faceted quartz crystals. Close-up of quartz or silicon dioxide (SiO2), one of the commonest minerals in the Earth's crust (12% by volume). The pure, colorless variety is also known as rock crystal and is used as a gemstone and highly prized by collectors. When it contains impurities, these impart a range of colors including white, yellow, pink, blue, green and smoky brown..

  • Map Lichen (Lecanora muralis) growing on granite bedrock along the shore of Georgian bay in Killarney Provincial park in Ontario, Canada.  This lichen grows less than 2 mm a year and are classified as Crustose lichens or map lichens.  These lichens create their own microhabitate.  Lichens also produce a weak acid which will eventually help dissolve the surface of the rock.

  • Scanning electron microscope image of Snake Liverwort (Conocephalum conicum).  This specimen was collected in the moist glens of the Finger Lake Region of New York State.  Liverworts (class Hepaticae) are related to mosses. They grow in damp habitats and are found on the ground and moist rock surfaces. They have no true vascular tissue, but are attached to the ground by means of root-like rhizoids.  Liverworts can reproduce vegetatively by fragmentation of the thallus or by producing specialized cell masses called gemmae.   The central structures in this image are the reproduction organs. Magnification is 125x and represents a section of the plant 1 mm wide...
