Shallow-Marine Architecture Knowledge Store

The next in a series of databases in the Ava Clastics suite is the Shallow-Marine Architecture Knowledge Store commonly referred to as SMAKS. The SMAKS database was created by the University of Leeds’ Shallow-Marine Research Group (SMRG), and is also available as part of a subscription to Ava Clastics.

Their exhaustive research is captured in a relational database storing hard and soft data about shallow-marine sedimentary systems. This data is derived from both original SMRG fieldwork studies and peer-reviewed literature syntheses. The database incorporates information from both modern and ancient systems that have been specifically selected because they are considered to represent potential analogues to hydrocarbon reservoirs hosted in shallow-marine rocks.

Shallow-Marine eBook Chapter

The SMAKS database is a system for the digital reproduction of all the essential features of shallow-marine sedimentary architecture. Learn more in this chapter introducing different aspects involved in analysing shallow-marine geology.

For Facies Modelling...

Build quantitative facies models that describe the distribution of architectural elements within deltaic and paralic settings. You can also characterise the scale, orientation and stacking of these elements and their style of juxtaposition relative to one another.

For Predictive Modelling...

You can use the data to predict the expected dimensions of architectural elements away from the well and predict the most likely arrangement of neighbouring elements.

For Comparative Analysis...

Compile exhaustive comparative statistics for different types of shallow-marine systems: for example, calculate dominant depositional processes, bar form thickness and width, and likely ichnofacies assemblages.


The database incorporates information from both modern systems and ancient successions in a sophisticated repository developed for the storage and structured retrieval of quantitative information relating to shallow-marine sedimentary architecture.


SMAKS accounts for the style of internal organisation of sedimentary bodies, their geometries, grain size, spatial distribution, and the hierarchical and spatial reciprocal relationships of genetic units that comprise these geological bodies.
