1. A process to describe vertical sequences of rocks using gestures, comprising: using a device with touchscreen, gesture recognition and multi-touch support to open a system that provides standardized vocabulary and icons, digital keyboard and the following columns: Context ( 1 ), Visible ( 2 ), Box ( 3 ), Particle Size ( 4 ), Color ( 5 ), Facies ( 6 ), Lithology ( 7 ), Structure ( 8 ), Fossil ( 9 ), Sorting ( 10 ), Roundness ( 11 ), Sphericity ( 12 ), Notes ( 13 ), Bioturbated Index ( 14 ), Organic Matter Content ( 15 ) and Hydrocarbon Level ( 16 ): selecting new description; entering a total length of a sample of vertical sequences of rocks; inserting initial and final depths of the sample of vertical sequences of rocks; inserting a new interval in a Visible column ( 2 ); choosing a type of rock in a Lithology column ( 7 ); inserting a particle size in a Particle Size column ( 4 ); inserting a type of rock structure in a Structure column ( 8 ); inserting a rock color in a Color column ( 5 ); inserting types of fossil in a Fossil column ( 9 ); inserting data in a Sorting column ( 10 ); inserting interval roundness in a Roundness column ( 11 ); inserting interval sphericity in a Sphericity column ( 12 ); inserting contents of organic matter present in a sample in an Organic Matter Content column ( 15 ); inserting bioturbation index in an interval in a Bioturbated Index column ( 14 ); inserting a hydrocarbon level in an interval in a Hydrocarbon Level column ( 16 ); inserting notes in a Notes column ( 13 ); inserting a code for an interval in a Facies column ( 6 ); changing a box size and a code where a sample is in a Box column ( 3 ); inserting a contact between intervals; optionally, inserting a new interval and repeating the whole process; and generating a report for data analysis.
