Match the intrusive igneous landforms listed in List-I with their corresponding structural and geometric characteristics in List-II:

  • LaccolithLarge dome-shaped intrusion with a planar horizontal base, fed by a vertical pipe-like conduit
  • LopolithSaucer-shaped intrusive body with a shallow basin structure concave toward the sky
  • PhacolithLens-shaped magma mass localized at the crest of an anticline or trough of a syncline
  • BatholithMassive granitic plutonic body exposed at the surface after extensive erosion, forming mountain cores

Cevap

Laccolith corresponds to the dome-shaped intrusion with a planar horizontal base; Lopolith corresponds to the saucer-shaped body concave toward the sky; Phacolith corresponds to the lens-shaped body at fold crests or troughs; Batholith corresponds to the massive plutonic rock body forming mountain cores.
Each intrusive landform is correctly matched to its specific structural morphology: Laccolith to the dome shape with a flat base, Lopolith to the saucer-shaped concave structure, Phacolith to the lens-shaped fold hinge intrusion, and Batholith to the massive granitic plutonic body.

Adım Adım Çözüm

1
Analyze the structural geometry of Laccolith
Laccolith matches with the dome-shaped intrusion having a flat horizontal base and a pipe feeder.
Viscous magma forces the overlying strata to arch upward, creating a dome structure over a flat base.
2
Analyze the structural geometry of Lopolith
Lopolith matches with the saucer-shaped intrusive body concave toward the sky.
As magma intrudes into structural basins, sagging under gravity produces a characteristic saucer shape.
3
Analyze the structural placement of Phacolith
Phacolith matches with the lens-shaped magma mass localized at anticline crests or syncline troughs.
Differential stresses during crustal folding create space at fold hinges for lens-like magma accumulation.
4
Analyze the structural characteristics of Batholith
Batholith matches with the massive granitic plutonic body forming mountain cores.
Batholiths represent the largest plutonic intrusions, forming deep beneath mountain systems.
