44
Q

Clay mineral use (low in…)

A

Electrical conductivity and thermal conductivity
Insulators

45
Q

Piezoelectricity example of mineral with this property and its use

A

Electric currents generated by stress applied

Quartz
Tell time

46
Q

Eight most abundant elements in Earth’s crust AND MANTLE

A

Oxygen (O), Silicon (Si), Aluminum (Al), Iron (Fe), Calcium (Ca), Sodium (Na), Potassium (K), Magnesium (Mg)

47
Q

Elements that make up the earths crust AND mantle

A

Oxygen(O), silica (Si),

48
Q

If you have a Fe 2O3 and Fe2 SiO4 which one will be easier to beneficiate the Iron (Fe) and why?

A

Majority of earth’s elements are found in greater quanitues in nonsilicates=extract
Silicates are refractory: low solubility and high melt. point (hard to extract)
Fe2O3-nonsilicate=beneficiate

49
Q

Light silicates

A

feldsbar, muscovite, quartz, clay

50
Q

pot

which feldspar group has striations?

A

plagioclase

51
Q

Habit of quartz

A

hexagonal with pyramid tips

52
Q

What’s the calcium-rich feldspar like?

A

gray, blue-gray, black

53
Q

What’s the sodium-rich feldspar like?

A

light color
pearly

54
Q

Dark silicate minerals

elements in it

A

proxenees, ampiboles, olivine, biotite, garnets

iron + mg

55
Q

How many directions of cleavage does augite have?

A

2 directions
90

56
Q

how many directions of cleavage does olivine have??

A

none

57
Q

what makes up the pyroxene group

A

augite

58
Q

what makes up the amphibole group

A

hornblende

59
Q

nonsilicates groups

A

sulfates, halides, carbonades, oxides, sulfides

60
Q

a silicate mineral that originates as a product of chemical weathering

A

clay minerals

61
Q

explanations for identical fossils in places separated thousands of kilometers of ocean

A
  1. rafting, land bridges, island stepping stones,
62
Q

rifting

A
  1. tensional forces creaste fractures and upwelling of mantle and upwarping of lithosphere
  2. thinning and stretching of lithosphere=crust breaks into large blocks which then sink to create a continentala rift valley
  3. linear sea–> deep ocean basin with mid oceanic ridge
63
Q

oceanic lithosphere components vs continental lithosphere

A

oceanic: basalt, iron and mg
continental: granitic

64
Q

rifitng of pangeao

A

creation of new ocean basin: Atlantic from north america and africa, atlantic opened up, separation of africa, india, antactica, asia and idia collided, baja separated from mexico

65
Q

what were scientists using magnetometers floor
what did vien and matthews fine

A

map variations in the stregth of earth’s magnetici field

Vine and Matthews fiund that the ocean floor is composed of hugh intensity and low intensity stripes of magnetism

66
Q

density of mantle

A

4.5

67
Q

density of core

A

10-13

68
Q

how did we get crust

A

chemical differeientation where melting of buyant masses of motlen rock rose to surface that were rich in oxygen and some heavy metals

`

69
Q

rock in upper most mantle

A

periodite

70
Q

what do we euse today for bathymetry and what did we use, what did th eus navy use

A

Today: sonar
past: echo sounders
sidescan sonar but it waasn’t bathymetry just shape pf floor
