Carbonate Petrography
Carbonate petrography is the study of limestones, dolomites and associated deposits under optical or electron microscopes greatly enhances field studies or core observations and can provide a frame of reference for geochemical studies.
25 strangest Geologic Formations on Earth
The strangest formations on Earth.
What causes Earthquake?
Of these various reasons, faulting related to plate movements is by far the most significant. In other words, most earthquakes are due to slip on faults.
The Geologic Column
As stated earlier, no one locality on Earth provides a complete record of our planet’s history, because stratigraphic columns can contain unconformities. But by correlating rocks from locality to locality at millions of places around the world, geologists have pieced together a composite stratigraphic column, called the geologic column, that represents the entirety of Earth history.
Folds and Foliations
Geometry of Folds Imagine a carpet lying flat on the floor. Push on one end of the carpet, and it will wrinkle or contort into a series of wavelike curves. Stresses developed during mountain building can similarly warp or bend bedding and foliation (or other planar features) in rock. The result a curve in the shape of a rock layer is called a fold.

330 million years old volcano discovered near Mullingar, Co Westmeath

How Mullingar might look with a volcano nearby |
The revelations were made in the most recent piece of the Government's Tellus program.
Flying at 90metres, air ship use innovation to see through Ireland's profound frigid stores and broad peat spread.
Specialists said the destinations will be of enthusiasm to organizations watchful for mineral stores.
"A comprehension of Ireland's topography is indispensable for natural, wellbeing and financial reasons and the information will be invited by a wide scope of partners for agrarian, radon aversion, groundwater security and mineral investigation purposes."
Tellus plans to finish a topographical jigsaw of the island of Ireland and wants to have a large portion of the nation secured before the end of 2017.
The Midlands discoveries are huge as they make up another bit of the jigsaw which started in 2007.
The fourth period of Tellus is in progress crosswise over eastern Ireland where the overview over Offaly, Kildare , Meath , Dublin and northern parts of Wicklow and Laois is just about 60 for every penny complete.
Right now the undertaking is centered around country district Dublin .
The uniquely prepared flying machine conveys three instruments on load up measuring attraction, conductivity and regular radiation of the stones and soils underneath.
Tellus is a piece of Ireland's earth science office, the Geological Survey of Ireland, established in 1845.
The overview is in charge of gathering land data and giving guidance and data including maps, reports and databases.
It is a Department's piece of Communications, Energy and Natural Resources and has around 50 staff.
