Who invented sequence stratigraphy?

Sequence stratigraphy is a recent methodology for stratigraphic interpretation, pioneered by Peter Vail in the mid 70’s (Vail et al 1977), that explains the complex geometries that sediments acquire as they fill accommodation in response to changes in rates of sedimentation, tectonic and eustatic movement.

How are sequence boundaries formed?

A sequence boundary forms when base level slowly drops and a lake converges. When a sequence boundary occurs in a shallow water or exposed environment, ferric oxide minerals increase.

What are the types of stratigraphy?

There are several types of stratigraphy that are described below.

• Geochronology – Radiometric Stratigraphy.
• Magnetostratigraphy.
• Stratigraphic Classification, Terminology and Procedure.
• Facies Stratigraphy.
• Quantitative Stratigraphy.
• Sequence Stratigraphy.

What is an erosional boundary?

A surface that separates older sequences from younger ones, commonly an unconformity (indicating subaerial exposure), but in limited cases a correlative conformable surface. A sequence boundary is an erosional surface that separates cycles of deposition.

What do you need to know about sequence stratigraphy?

Sequence stratigraphy is the science of subdividing a sedimentary basin fill into individual sequences of deposition (hence the name), which can then be linked to changes in the two fundamental parameters of sediment supply and accommodation (the amount of space available for deposition).

What is the cross section of a stratigraphic diagram?

Stratigraphic cross-section (upper) and chronostratigraphic (Wheeler) diagram lower, illustrating the chronostratigraphic potential of a subaerial unconformity (bold black lines, gray region).

How to create 3D stratigraphic models and diagrams?

Home > Borehole Manager – Modeling & Diagrams > Stratigraphy Tools > Modeled Stratigraphy Diagrams > Creating 3D Stratigraphic Models and Diagrams Use this program to: Interpolate grid models for the upper and lower surfaces of the project’s stratigraphic units (all units or selected ones) – or – read grid models that you’ve already created.

How to create a stratigraphic diagram in rockplot3d?

The completed diagram will be displayed in a RockPlot3D window, with volume and mass of each formation noted. The program offers optional creation of a 3D solid model (.RwMod file) representing the stratigraphy surfaces layered from the bottom up, for use with other analysis tools.
