What is a Isochore map?

What is a Isochore map?

1. n. [Geology] A contour connecting points of equal true vertical thickness of strata, formations, reservoirs or other rock units. A map that displays isochores is an isochore map. The terms isopach and isopach map are incorrectly used interchangeably to describe isochores and isochore maps.

What does an Isochore map represent one sentence?

Isochore maps measure the thickness from a point on the upper surface straight down to the corresponding point on the lower surface. Isopach maps display the stratigraphic thickness between an upper and lower horizon.

What are Isopachytes?

(ˈaɪsəʊˌpæk ) or isopachyte (ˌaɪsəʊˈpækaɪt ) noun. geology. a line on a map connecting points below which a particular rock stratum has the same thickness.

How do I create an Isochore map?

How do I make an isochore or isochron map in Insight?

  1. Open Map View and begin a Horizon Maths operation (see Horizon Maths).
  2. At the Inputs section, input horizon ‘h1’ and ‘h2’. For an isochore map, set the property as TVDSS (m).
  3. At Formula, insert the formula: h1 – h2.
  4. Select the output vertical dimension.

What is an Isochore in DNA?

From Wikipedia, the free encyclopedia. In genetics, an isochore is a large region of DNA (greater than 300 kb) with a high degree uniformity in guanine (G) and cytosine (C): G-C and C-G (collectively GC content).

How do you draw an isopach map?

To construct an isopach map from borehole logs, one locates the top and bottom of the stratigraphic unit on a given log, subtracts the lesser depth from the greater, and plots the resulting thickness on a map. Repetition for each of the available logs generates the data that are then contoured on the map.

What is an isochore Class 11?

Isochore is the plot between P and T for a definite amount of a gas at a constant volume.

What is the difference between isopach and isochore?

An isopach map displays lines of equal thickness in a layer where the thicknesses are measured perpendicular to the layer boundaries. Isopach maps are also referred to as True Stratigraphic Thickness (TST) maps. An isochore map displays lines of equal thickness in a layer where the thicknesses are measured vertically.

Which is the correct definition of an isochore map?

A contour connecting points of equal true vertical thickness of strata, formations, reservoirs or other rock units. A map that displays isochores is an isochore map. The terms isopach and isopach map are incorrectly used interchangeably to describe isochores and isochore maps.

What’s the difference between an isopach and an isochore?

An isopach is a line that connects points of equal true thickness (i.e. measured perpendicular to bedding), whereas… an isochore is a line that connects points of equal vertical thickness . Fig. 1.-

How is the thickness of an isopach map measured?

An isopach map displays lines of equal thickness in a layer where the thicknesses are measured perpendicular to the layer boundaries.

How do you calculate the isochron of stratigraphic thickness?

To calculate the isochron, or time interval map, subtract the top horizon time from the base horizon time. For flat stratigraphy, this would also result in the isopach: vertical thickness is the same as stratigraphic thickness. With increasing dip, the difference between vertical thickness and stratigraphic thickness measurements becomes larger.
