2 A Rock is A group of minerals that have been put together in several different ways.

3 Depending on how they are put together, rocks are classified as: 1. Sedimentary 2. Igneous 3. Metamorphic

4 Sedimentary Rocks are formed by several different processes.

5 1. Deposition, Compaction and Cementation (Lithification) of Sediments.

6 2. Crystallization or Chemical Reaction of Minerals in Solution in water.

7 Igneous Rocks are formed by the Crystallization, by Cooling and Hardening, of molten Magma (molten rock below ground) or Lava (molten rock above ground).

8 Metamorphic rocks are formed by the Recrystallization or Chemical Change of minerals due to Heat and/or Pressure.

9 Let s Focus on

10 How are Igneous Rocks Classified?

11 Igneous Rocks are classified based upon several different qualities or characteristics: 1. Mineral Composition 2. Location of Crystallization 3. Texture of Grain Size

12 1. Igneous rocks are identified based upon Mineral Composition (high or low Silica content)

13 High Silica rocks are called Felsic Igneous Rocks and are light in color.

14 Felsic Rocks and Minerals

15 Silica-Rich, or Felsic Rocks Igneous rocks that have a Silicate composition of 65% or more are considered to be Felsic.

16 Low Silica rocks are called Mafic Igneous Rocks, and are dark in color.

17 Mafic Rocks

18 Silica-Poor, or Mafic Rocks Igneous rocks that have a Silicate composition of 45-50% or less are considered to be Mafic.

19 Igneous rocks that have a Silicate composition of 50-65% are considered to be Intermediate or Andesitic (named after a rock made from a mixture of Mafic magma and minerals from Felsic country rock ).

20 Igneous rock can be classified by Silica and Oxide content

21 Pure Silica

22 2. Igneous Rocks are identified based upon where they are formed (above or below ground).

23 Igneous rocks formed underground from Magma are called Plutonic or Intrusive rocks. Notice the large crystals

24 Igneous rocks formed above ground from lava are called Extrusive or Volcanic rocks. Felsite Obsidian Rhyolite

25 3. Igneous Rocks are identified based upon Texture (size of mineral crystals) Glassy Large-Grained

26 Texture of Grain Size is evidence of rate of cooling; The faster magma or lava cools, the smaller the size of the crystals in the solidified material will be. Pumice Obsidian

27 When Magma cools slowly underground, large crystals have time to form. Therefore, Igneous rocks with large crystals are most likely Plutonic.

28 When Lava cools rapidly above ground, crystals have a limited time to form. Therefore, Igneous rocks with small or no crystals are most likely Volcanic.

29 Igneous Rock Textures

30 Obsidian-Glassy Felsic

31 Basalt- Fine-grained Mafic

32 Andesite- Fine-grained Intermediate

33 Rhyolite- Fine-grained Felsic

34 Granite- Coarse-grained Felsic

35 Diorite- Coarse-grained Intermediate

36 Gabbro- Coarse-grained Mafic

37 Pumice- Vesicular Felsic

38 Vesicular Basalt- Mafic

39 Scoria-Vesicular Mafic

40 Basalt Porphyry- Mafic

41 Rhyolite Porphyry-Felsic

42 Andesite Porphyry- Intermediate

43 How does Mineral Composition of magma or lava affect an Igneous Rock or the molten material that it forms from?

44 High Silica content causes Felsic Magma to be thick, or viscous, and slow-flowing.

45 Felsic Dome

46 Felsic Dome

51 Low Silica content causes Mafic Magma to be thin or low-viscosity, and fast-flowing.

58 Flood Basalt Plateau

59 Igneous rock can be classified based on where they were formed. (location of Crystallization)

60 Intrusive Igneous Rock forms structures such as

61 Dikes Dike: Sheet-like Igneous rock that cuts across the structure of pre-existing rock.

62 Dike

63 Volcanic Dike Volcanic Neck

64

65

66 This would form a Dike.

67 Sills Sills: Sheet-like Igneous rock that lies parallel to the layering of pre-existing rock.

68 Sill

69 Sill

70 Laccoliths Laccoliths: A Laccolith is a vertically developed sill.

71 Exposed/Eroded Laccoliths

72 Batholiths Batholiths: A Batholith is a large Plutonic mass of Igneous Rock (old Magma bubble ).

75 Enchanted Rock-Texas

78 Extrusive Igneous Rock forms structures such as

79 Felsic Lava Flows

80 Mafic Lava Flows Pahoehoe Lava

81 Domes

82 Flood Basalt Plateaus- Mafic Lava

84

85 Tephra or Ash Deposits

89 Volcanic Cones

90 Composite Cone (lava and Tephra)- Felsic

91 Cinder Cone- Mafic Lava
