Lode

In geology, a lode is a deposit of metalliferous ore that fills or is embedded in a fissure (or crack) in a rock formation or a vein of ore that is deposited or embedded between layers of rock. The current meaning (ore vein) dates from the 17th century, being an expansion of an earlier sense of a ‘channel, watercourse’ in late Middle English, which in turn is from the 11th-century meaning of lode as a ‘course, way’.

The generally accepted hydrothermal model of lode deposition posits that metals dissolved in hydrothermal solutions (hot spring fluids) deposit the gold or other metallic minerals inside the fissures in the pre-existing rocks. Lode deposits are distinguished primarily from placer deposits, where the ore has been eroded out from its original depositional environment and redeposited by sedimentary forces. A third process for ore deposition is as an evaporite.

A stringer lode is one in which the rock is so permeated by small veinlets that rather than mining the veins, the entire mass of ore and the enveined country rock is mined. It is so named because of the irregular branching of the veins into many anastomosing stringers, so that the ore is not separable from the country rock.

Bachelor's degree

A bachelor's degree (from Middle Latin baccalaureus) or baccalaureate (from Modern Latin baccalaureatus) is an undergraduate academic degree awarded by colleges and universities upon completion of a course of study lasting three to seven years (depending on institution and academic discipline). In some cases, it may also be the name of a second graduate degree, such as the Bachelor of Laws (LL.B.), Bachelor of Education (B.Ed.), Bachelor of Civil Law (B.C.L.), Bachelor of Music (B.Mus.), Bachelor of Philosophy (B.Phil.), or Bachelor of Sacred Theology (B.S.Th.) degrees, which in some countries are only offered after a first graduate/bachelor's degree.

The term "bachelor" in the 12th century referred to a knight bachelor, too young or poor to gather vassals under his own banner. By the end of the 13th century, it was also used by junior members of guilds or universities. By folk etymology or wordplay, the word baccalaureus came to be associated with bacca lauri ("laurel berry") in reference to laurels being awarded for academic success or honours.
