Zorluk: OrtaRock Types, Formation, and Economic Importance

Match each rock specimen listed under Column I with its precise genetic formation process and primary economic application described under Column II.

  • BauxiteResidual sedimentary deposit produced by intense tropical weathering and leaching; serves as the principal commercial ore for aluminum extraction.
  • SyenitePlutonic intermediate igneous rock formed by slow cooling of quartz-poor magma underground; utilized as durable dimension stone and coarse construction aggregate.
  • SlateLow-grade foliated metamorphic rock derived from the alteration of clay-rich shale; split along cleavage planes for roofing tiles and electrical panels.
  • TravertineChemical sedimentary rock precipitated from calcium carbonate-saturated hot mineral springs; widely used as decorative interior wall cladding and flooring.

Cevap

Bauxite corresponds to the residual sedimentary deposit serving as aluminum ore; Syenite corresponds to the plutonic intermediate igneous rock used in construction; Slate corresponds to the low-grade foliated metamorphic rock derived from shale used for roofing; Travertine corresponds to the chemical sedimentary mineral spring deposit used for decorative cladding.
Each rock specimen is accurately paired with its geological formation mechanism and economic application: Bauxite is a residual sedimentary aluminum ore; Syenite is a plutonic igneous construction stone; Slate is a foliated metamorphic material derived from shale; and Travertine is a chemically precipitated limestone used in architecture.

Adım Adım Çözüm

1
Identify the origin and economic utility of Bauxite.
Bauxite is a residual sedimentary rock formed through intense leaching (laterization) in warm, humid tropical climates and is the chief source of aluminum.
Recognizing the chemical weathering process distinguishes Bauxite from mechanically formed sedimentary rocks.
2
Determine the genesis and industrial application of Syenite.
Syenite is a coarse-grained intrusive igneous rock similar to granite but lacking quartz, mined for heavy structural work and decorative stone.
Plutonic rocks crystallize slowly beneath the surface, giving Syenite its coarse crystalline texture.
3
Analyze the metamorphic origin and physical property of Slate.
Slate develops from shale protoliths subjected to low-grade regional heat and pressure, imparting a planar cleavage that makes it easy to split into thin sheets.
Foliation characteristics directly determine its commercial utility as durable roofing tiles.
4
Distinguish the precipitative origin of Travertine.
Travertine is formed by inorganic precipitation of calcium carbonate at geothermal springs and is cut and polished for architectural tiles.
Chemical precipitation differentiates Travertine from organic or clastic limestones.
