   Chapter 1: Hello everyone. 295s · Speaker 1

   Hello everyone. Assalamu alaikum. This is Dr. Adil Saeed and today we are going to continue our structural geology two classes. This is class number or lecture number four which is mainly focuses on some important topic for today which is i…

   Chapter 2: along the axis of the Oh, that is longitudinal joint. 301s · Speaker 2

   along the axis of the Oh, that is longitudinal joint. There is B, diagonal joints. Look at B, which is moving diagonally. That is moving longitudinally and B is moving diagonally. And number C, which is down there, it is transfer joints, tr…

   Chapter 3: having a column like so we call it columnar joints we can have also columnar joint is this way from the top view that is a cross section of the top view so if you go is a side view you are going to find them line after line after line in terms of column or bars so this is from the top view or cross section view then this is what is columnar joint look alike and it has formation that this is the shape and it could be reacted along these joints with a tension so that to form a hexagonal cooling joints when the material is cool so that the heat is moving up or moving away from the body and then the body shrink shrink become more shorter than fracture Take place so that the fracture is taking place in six and in hexagonal ways In a hexagonal ways. 120s · Speaker 1

   Chapter 4: and also the joints could be represented along the fracture of the fault zone and that is simply forming almost two joints the first one which is will be longitudinal along the fault plane the second one will be conjugate at 60 degrees so that you can represent it also with a Rouse diagram on the left on the right this is fracture and that is fracture so that the angle between those two might be around 60 degrees so that those two joints now forming something called columnar joints could be columnar shear fracture and this is the rose diagram showing the distribution of dip of two sets of fractures associated with the normal fault this is the normal fault and those two sets of fractures associated with it indicating the conjugate sets of shear fracture. 72s · Speaker 2
