Verified Answer
In igneous and metamorphic rocks, minerals may occur in the .............
In igneous and metamorphic rocks, minerals may occur in various locations within the rock formation. The minerals can be found in:
Cracks:
- Cracks or fissures within the rock provide spaces for minerals to accumulate.
- These cracks can be formed due to cooling and contraction of the rock or due to tectonic forces.
Crevices:
- Crevices are narrow openings or gaps within the rock.
- These gaps can be formed by weathering and erosion processes or by the movement of rock layers.
Faults or joints:
- Faults and joints are fractures in the rock where there has been displacement.
- These fractures can create pathways for mineral-rich fluids to flow and deposit minerals.
Beds:
- Beds refer to layers or strata of rock.
- Minerals can be present within these layers, either as primary minerals that formed during the rock's formation or as secondary minerals that have been deposited later.
Based on the given options, minerals can occur in cracks and crevices (i and ii) as well as in faults or joints (iii). Therefore, the correct answer is option B: Only (i), (ii), and (iii).

In igneous and metamorphic rocks, minerals may occur in the .............
In igneous and metamorphic rocks, minerals can occur in various locations within the rock. The question asks about the possible occurrence of minerals in cracks, crevices, faults or joints, and beds. Let's examine each of these options:
Cracks:
- Cracks refer to small fractures or fissures in the rock.
- Minerals can be found filling in these cracks, forming vein-like structures.
- This occurs when hot fluids containing dissolved minerals enter the cracks and then cool and solidify, leaving behind mineral deposits.
Crevices:
- Crevices are narrow openings or gaps in the rock.
- Similar to cracks, minerals can be found filling in these crevices.
- The process of mineral deposition is the same as in cracks, with hot fluids entering and cooling to form mineral deposits.
Faults or Joints:
- Faults and joints are larger fractures or breaks in the rock.
- Minerals can occur along these fault lines or within the joints.
- When the rock undergoes tectonic forces and fractures, minerals can be deposited in these areas.
Beds:
- Beds refer to layers or strata within the rock.
- Minerals can occur within these layers, either as individual mineral grains or as aggregates within the rock matrix.
- The minerals present in these beds can provide important information about the geological history and formation of the rock.
Based on the above explanations, the correct answer is option B, which states that minerals may occur in cracks, crevices, and faults or joints. These locations provide opportunities for mineral deposition during the formation of igneous and metamorphic rocks. It is important to note that the occurrence of minerals in these locations can vary depending on the specific rock type and geological processes involved.
Cracks:
- Cracks refer to small fractures or fissures in the rock.
- Minerals can be found filling in these cracks, forming vein-like structures.
- This occurs when hot fluids containing dissolved minerals enter the cracks and then cool and solidify, leaving behind mineral deposits.
Crevices:
- Crevices are narrow openings or gaps in the rock.
- Similar to cracks, minerals can be found filling in these crevices.
- The process of mineral deposition is the same as in cracks, with hot fluids entering and cooling to form mineral deposits.
Faults or Joints:
- Faults and joints are larger fractures or breaks in the rock.
- Minerals can occur along these fault lines or within the joints.
- When the rock undergoes tectonic forces and fractures, minerals can be deposited in these areas.
Beds:
- Beds refer to layers or strata within the rock.
- Minerals can occur within these layers, either as individual mineral grains or as aggregates within the rock matrix.
- The minerals present in these beds can provide important information about the geological history and formation of the rock.
Based on the above explanations, the correct answer is option B, which states that minerals may occur in cracks, crevices, and faults or joints. These locations provide opportunities for mineral deposition during the formation of igneous and metamorphic rocks. It is important to note that the occurrence of minerals in these locations can vary depending on the specific rock type and geological processes involved.
