Kinzers Formation

Kinzers Formation is a earth science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Kinzers Formation rather than just read about it. In short: The Kinzers Formation is a geologic formation in Pennsylvania. It preserves fossils dating back to the fourth stage of the Cambrian Period.

Key takeaways

Kinzers Formation belongs to earth science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Kinzers Formation to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Kinzers Formation from memory before moving on to harder problems.

Reference excerpt

The Kinzers Formation is a geologic formation in Pennsylvania. It preserves fossils dating back to the fourth stage of the Cambrian Period. The base of the Kinzers Formation is primarily a dark-brown shale. The middle is a gray and white spotted limestone and, locally, marble having irregular partings. The top is a sandy limestone which weathers to a fine-grained, friable, porous, sandy mass. Wilshusen formally divided the Kinzers into three members along these lines in his 1979 map of York, Pennsylvania. The members are called the Earthy Buff Limestone Member, Pure Limestone Member, and Shale Member.

Type section Named from exposures at a railroad cut at Kinzers, Lancaster County, Pennsylvania.

Other outcrops The Kinzers overlies the Vintage Dolomite at the type section of the Vintage at a railroad cut at Vintage, Pennsylvania.

High quality fossil specimens (Lagerstätte) were obtained from the Noah Getz Quarry, one mile north of Rohrerstown, Pennsylvania, but the quarry location is overgrown and disturbed by development. The fossils are from the Emigsville Member, and include the trilobite Olenellus thompsoni, the radiodont Lenisicaris pennsylvanica, the hymenocarine arthropod Tuzoia getzi, the edrioasteroid echinoderm Yorkicystis haefneri, and the hemichordate nest Margaretia dorus. The Kinzers Formation is also notable for preserving one of the most diverse radiodont faunas of the Cambrian period, with at least ten species known, including members of the tamisiocarididae, anomalocarididae, and amplectobeluidae families. The sponge Hazelia walcotti has also been found in the Kinzers. It is one of few sponges known from the Cambrian period of North America.

Worked examples

Example 1 — a first encounter with Kinzers Formation

Start with the simplest possible case. Write down what Kinzers Formation claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In earth science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Kinzers Formation before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Kinzers Formation ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Kinzers Formation

In research: Kinzers Formation appears in earth science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Kinzers Formation in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Kinzers Formation is common in secondary-school and first-year university syllabi. It links to neighbouring topics Cambrian geology of Pennsylvania, Cambrian south paleopolar deposits, Cambrian southern paleotemperate deposits, so understanding it makes those chapters shorter.
In everyday life: Look for Kinzers Formation outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
