Keep in mind that the same cuts of beef can have different names. For example, a boneless top loin steak may also be called a strip steak, club sirloin steak or N.Y. strip steak. Other tips when choosing cuts of beef: 1  Choose cuts that are graded Choice or Select instead of Prime, which usually has more fat. 2  Choose cuts with the least amount of visible fat (marbling). 3  When selecting ground beef, opt for the lowest percentage of fat. 4  Limit consumption of organs, such as liver, to about 3 ounces (85 grams) a month.
Some limestones form from the cementation of sand and / or mud by calcite (clastic limestone), and these often have the appearance of sandstone or mudstone. As calcite is the principle mineral component of limestone, it will fizz in dilute hydrochloric acid.imestone is a sedimentary rock consisting of more than 50% calcium carbonate (calcite-CaCO 3). There are many different types of limestone formed through a variety of processes.
oolitic limestone Oolitic limestone is a carbonate rock made up mostly of ooliths (or ooids) which are sand-sized carbonate particles that have concentric rings of CaCO 3. These rings are formed around grains of sand or shell fragments that were rolled around on the shallow sea floor, gathering layer after layer of limestone. Portland limestone is an example of an oolitic limestone. This limestone formed in a shallow sea, rather like the modern Bahamas, near the end of the Jurassic period (~135 million years ago). The rock has an even structure rather like cod roe and it can therefore be cut or sculpted in any direction.
