Stock (geology)

In geology, a stock is a discordant igneous intrusion having a surface exposure of less than 40 sq mi (100 km²), differing from batholiths only in being smaller. Most stocks are probably the cupolas of hidden batholiths. Circular or elliptical stocks may have been vents feeding former volcanoes.

Geology

Geology (from the Greek γῆ, gē, i.e. "earth" and -λoγία, -logia, i.e. "study of, discourse") is an earth science comprising the study of solid Earth, the rocks of which it is composed, and the processes by which they change. Geology can also refer generally to the study of the solid features of any celestial body (such as the geology of the Moon or Mars).

Geology gives insight into the history of the Earth by providing the primary evidence for plate tectonics, the evolutionary history of life, and past climates. Geology is important for mineral and hydrocarbon exploration and exploitation, evaluating water resources, understanding of natural hazards, the remediation of environmental problems, and for providing insights into past climate change. Geology also plays a role in geotechnical engineering and is a major academic discipline.

Geologic materials

The majority of geological data comes from research on solid Earth materials. These typically fall into one of two categories: rock and unconsolidated material.

Country rock (geology)

Country rock is a geological term meaning the rock native to an area. It is similar and in many cases interchangeable with the terms basement and wall rocks.

The term is used to denote the usual strata of a region in relation to the rock which is being discussed or observed.

The following are areas in geology when the term country rock is used;

Stock

The stock (also capital stock) of a corporation constitutes the equity stake of its owners. It represents the residual assets of the company that would be due to stockholders after discharge of all senior claims such as secured and unsecured debt. Stockholders' equity cannot be withdrawn from the company in a way that is intended to be detrimental to the company's creditors.

Shares

The stock of a corporation is partitioned into shares, the total of which are stated at the time of business formation. Additional shares may subsequently be authorized by the existing shareholders and issued by the company. In some jurisdictions, each share of stock has a certain declared par value, which is a nominal accounting value used to represent the equity on the balance sheet of the corporation. In other jurisdictions, however, shares of stock may be issued without associated par value.

Shares represent a fraction of ownership in a business. A business may declare different types (classes) of shares, each having distinctive ownership rules, privileges, or share values. Ownership of shares may be documented by issuance of a stock certificate. A stock certificate is a legal document that specifies the amount of shares owned by the shareholder, and other specifics of the shares, such as the par value, if any, or the class of the shares.

Stock (food)

Stock is a flavoured liquid preparation. It forms the basis of many dishes, particularly soups and sauces. Making stocks involves simmering animal bones and/or meat, seafood, or vegetables in water and/or wine, adding mirepoix or other aromatics for more flavour.

Preparation

Traditionally stock is made by simmering various ingredients in water. A newer approach is to use a pressure cooker. The ingredients may include some or all of the following:

Today, ready-made stock and stock cubes consisting of dried, compressed stock ingredients are readily available. These are commonly known as bouillon cubes, as cooking base in the US, or as Oxo cubes in Britain, after a common brand of stock cube sold there.

Comparison with broth

The difference between broth and stock is one of both cultural and colloquial terminology but certain definitions prevail. Stock is the liquid produced by simmering raw ingredients: solids are removed, leaving a highly flavored liquid. This yields classic stock as made from beef, veal, chicken, fish and vegetables.

Stock (publishing house)

Stock is a French publisher, a subsidiary of Hachette Livre, which itself is part of the Lagardère Group.

It was founded in the 18th century by André Cailleau, who was succeeded in 1753 by Nicolas-Bonaventure Duchesne, who published Voltaire and Rousseau. At the beginning of the 19th century, the publisher was called "Au Temple du goût". In the middle of the century it changed hands and was eventually bought up by Pierre-Victor Stock, who ran it from 1877 to 1921 and gave it its current name.

During the Dreyfus affair, Stock published many essays on the subject, including Dreyfus's own Lettres d'un innocent. In his memoir Mémorandum d'un éditeur, Pierre-Victor Stock estimated that Stock had published around 150 works connected with the Dreyfus affair.

In the early 20th century, Stock ran into legal and financial difficulties. It was taken over in 1921 by Maurice Delamain and Jacques Chardonne, who renamed it "Stock, Delamain et Boutelleau". In 1961, Delamain and Chardonne sold Stock to Hachette.
