2016-9-26 · Elmira is a medium-to-large gastropod of uncertain systematic affinity, which has so far been reported only from a presumably Eocene methane-seep deposit in Cuba. This study reports a mass occurrence of Elmira shimantoensis Kiel and Nobuhara sp. nov. from a Late Cretaceous hydrocarbon-seep deposit in Shikoku, Japan, called the Sada Limestone. Its …

Limestone | Types, Properties, Composition, Formation, Uses

 · Limestone is a sedimentary rock such as greater than 50% calcium carbonate ( calcite – CaCO3). There are many exceptional kinds of limestone formed thru a ramification of tactics. It may be precipitated from water ( non-clastic, chemical or inorganic limestone), secreted by using marine organisms including algae and coral (biochemical ...

Influence of meteorological factors on rockfall occurrence ...

The influence of meteorological conditions on rockfall occurrence has been often highlighted, but quantitative analyses are rare. A near-continuous survey of a limestone cliff has shown that the rockfall frequency can be multiplied by 7 during freeze-thaw episodes and 26 when the mean rainfall intensity (since the beginning of the rainfall episode) is higher than 5 mm h −1.
