Lecture 25/01/2017 Flashcards
essential macronutrients for plants to succeed
N (i.e., nitrates)
P (i.e., phosphates)
K (i.e., potash)
“dimension stone”
stone for building facades, gravestones, etc.
“drilling muds”
ie., liquid drilling aid containing bentonite (a volcanic ash containing clay minerals).
What is the role of sands in Hydrofracking (‘fracking’) solutions?
To keep open the fractures in rock which have been plied apart by water pumped at high pressure.
Provide an example of a mineral that could be substituted for a metal.
Feldspars: ceramic bearings
Experimental: ceramics used in engine blocks.
Provide an example of rock/mineral synthesis
diamonds
The value of indust. rocks and minerals can be determined by where they are found. (i.e., found close to where they are being used). Provide an example.
Gravel pits proximate to road construction requiring gravel.
What’s so great about the Mica mineral group?
Occurs in sheets with platelets and has anti corrosion properties.
What element is Potash associated with?
K
Does K accumulate as a marine evaporite or a marine sedimentary rock?
marine evaporite
How does P accumulate?
Through the formation of marine sedimentary rocks, nodules, and guano.
What’s the mode of formation for nitrates?
Nitrates formed through the chemical combustion of nitrogen and oxygen or ‘nitrogen fixation’.
Sulphur is a native element in ________ districts
volcanic
What is the mineral name for Na?
halite
Brines are found more frequently shallower or deeper in Earth’s Surface?
deeper
Brines and Brackish water, which is found deeper in Earths’ surface?
brines
Provide some examples of Dimension stone.
1) Marble (counter-tops)
2) Granite (counter-tops and headstones)
3) Slate (roof and patio applications
4) sandstone (carving and building)
*Marble is softer than granite
Provide examples of rocks and minerals used in the construction industry.
- crushed stone (e.g., limestone, dolomite, basalt)
- cement (i.e., calcite [limestone] and gypsum)
- plaster (gypsum)
- brick (i.e., clays)
- glass (i.e., quartz, silica, feldspar, etc.)
- asbestos insulation
- gypsum board (aka, ‘drywall’)
What geological process produces Slate?
metamorphism (i.e., intense folding).
What is Gypsum used for in construction?
‘Drywall’ or ‘gypsum board’
What is the metric for ‘Oil gravity’?
API (American Petroleum Industry) degrees (i.e., as a heavy oil, Tar Sands would be considered to have a high API).
What’s bentonite?
bentonite - a volcanic ash containing clay minerals.
