This is a small plate of Jurassic aged brittle stars (Sinosura kelheimense & Ophiopetra lithographica) from the famed Solnhofen Limestone of Germany The Solnhofen limestones is a famous Lagerstätte in Germany that offer amazing preservation of Upper Jurassic fossils It is where one of the most famous fossils of all time, Archaeopteryx was ....
In this study, the roles of water as a pore fluid, and of temperature, on the deformation and failure of a micritic limestone (white Tavel limestone, porosity 147 per cent) were investigated ....
Plasticity theory for rocks is concerned with the response of rocks to loads beyond the elastic limitHistorically, conventional wisdom has it that rock is brittle and fails by fracture while plasticity is identified with ductile materials In field scale rock masses, structural discontinuities exist in the rock indicating that failure has taken place...

Limestone vs Sandstone Characteristics Though some rocks look identical, they have certain characteristics which distinguish them from others Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc Limestone vs Sandstone characteristics assist us to distinguish and recognize rocks...
A brittle material is one that fails by fracturing after only a very small amount of plastic strain has occurred Sandstones tend to be made up of quartz and feldspars which are themselves brittle...
Both limestone and travertine are fashionable products but limestone is absolutely better suited to high-traffic areas Travertine is formed under less pressure than limestone, making it naturally more brittle It also has a tendency to chip or crack, especially under extremely hot or cold temperatur...
Sedimentary- layers, soft and brittle (ex: limestone, sandstone) Metamorphic- shiny, ribbon like layers, bubbles (ex: gneiss, marble) The BIG Three: When a geologist stumbles upon a mountain of mysterious mystical rocks, they know that there are three main types of rocks that may make up that mountain Each type of rock has characteristics that ....

The Tavel limestone is a white micritic limestone with relatively large clasts and equant pores embedded in a fine-grained matrix At a pressure of 30 MPa, stress-induced cracks was observed to emanate from pre- existing pores, and brittle failure developed by the coalescence of such pore-emanated wing cracks preferentially aligned with the ....
