Rock Chalk Jayhawk KU. Chalk rock is a slang term for Xanax. Ayyy foo , you got any of that chalk rock? As the soft chalk weathers away, flint nodules fall to the beach below. Much chalk was deposited during the Cretaceous Period of geologic time. It was a time of global high sea levels that began at the end of the Jurassic Period about million years ago and the beginning of the Paleogene Period about 66 million years ago.
During the Cretaceous, warm waters of epeiric seas, seas that flooded continental crust during sea level highs, existed in many parts of the world. Warm waters of the epeiric seas facilitated chalk deposition because calcium carbonate is more soluble in cold water rather than warm water, and because organisms that produce calcium carbonate skeletal debris will more actively produce in warm water.
More chalk formed during the Cretaceous Period than in any other period in geologic history. The Cretaceous received its name after the Latin word creta , which means "chalk". Coarse Chalk: A specimen of chalk with a coarse grain size from the Cretaceous-age Kristianstad Basin collected at a gravel pit near the community of Luneburg, northern Germany. This specimen is from the geological collection of the City Museum of Berlin, and the image is used under a Creative Commons license.

An examination with a hand lens will often reveal the fossil content, separating it from gypsum. The acid reaction will surprise you if you are used to testing other types of limestone and have never tested chalk. When you apply a drop of acid, capillary action pulls it deep into pore spaces of the specimen.
There, the enormous surface area of calcium carbonate that contacts the drop of acid usually produces a spectacular effervescence. Instead of holding the specimen in your hand during the test, place it on surface that will not be damaged by the acid, with a couple paper towels beneath it. Fields are shown in yellow, well locations are shown in green and red.
