Question
The industrial revolution began the rapid consumption of mineral deposits. Mineral deposits are []. Found and assayed volumes of desired mineral elements and compounds are called resources. Those parts of resources that can be mined profitably are called reserves (or ores). Economic decides. Some industrialized countries, initially rich in mineral resources at the beginning of the industrial revolution such as England, or always poor in mineral [] such as Japan, now must import almost all that they use. World reserves for many essential metals at current rate of world consumption are to run out alarmingly soon: Of these; silver [()], tin ([]), lead ([]), gold ([]), and copper (Cu), were important in the preindustrial world. How they were found by prospectors tells the common story that can be told for tin in Cornwall, England. From when the early settlers arrived in Cornwall from Europe around 2300 BC, to the later half of the 17th Century, Cornish mining was largely limited to placer mining. Having exhausted the [] deposits, the search was then for the mother load (the source rock). The country rock of Cornwall was originally a mudstone of Devonian age. This was intruded during the Carboniferous [] by coarse-grained biotite granite. Cassiterite, and associated wolframite, metal sulphides and fluorite, is within steeply inclined, thin, tourmaline-rich quartz veins that extend into the country rock from the outer part of stocks of the granite (now widely exposed by erosion) The cassiterite typically forms -1% of mined lodes (vein material). Metamorphic aureoles about the granite stocks are "killas" (an old mining term) of banded hornfels and tourmaline schist at the contact and away from there, as metamorphic grade [], mica-rich phyllites, and furthest away, slates spotted with cordierite. Towards the end of the 17 Century gunpowder became used. Controlled explosions helped in breaking up the rock. Shallow surface excavations were made. In 1710, the first steam driven water pump was installed in Cornwall, allowing mine shafts and workings to take place [] sea level. By 1801 there were 75 mines employing around 16,000 people in Cornwall. By 1862 there were around. 346 mines in Cornwall, with a working population of 50,000. In 1866, the tin industry was riding high producing 10,000 tonnes of tin a year-about half the world's production. 1985- Tin prices plummet on the Tin Exchange. 1986-Closure of Geevor Mine in Cornwall. 1998-South Crofty, the last Cornish tin mine, closed.Explanation / Answer
The industrial revolition began the rapid consumption of mineral deposits. Mineral deposits are non renewable.
Some industrialized countries,initially rich in mineral resources at the beginning of industrial revolution such as England,or always poor in mineral resoures such as Japan,now must import almost all they use.
All of these silver(Ag),tin(Sn),lead(Pb),gold(Au) and copper(Cu)
Having exhausted the placer deposits,the scratch was then for the mother load.
This was intruded during the Carboniferous period by coarse grained biotite granite,cassiterite and associated wolfromite.
As metamorphic grade decreases,mica rich phyllites and furthest away,slates spotted with cordeirite.
In In1710,the first steam driven water pump was installed in Cornwell,allowing mine shafts and workings to take place below sea level.
