ANTHROPOCENE: GEOLOGIC TIME DEPENDING OF THE EVOLVING STATE OF THE HUMAN PRODUCTIVE FORCES

Since the 2002 the Anthropocene was established as a new epoch proposal within the Quaternary, with considerable questioning by several authors. Preliminary interpretations for this geologic time suggests a time designation conditioned by the historical context of social relationships and modes of production. However, if only the social development of the Homo sapiens is considered (agriculture, industry, nuclear weapons, etc), then the Anthropocene time could be defined as a social or even a cultural time, rather than a geological interval. Nevertheless, the dominant conception and actions over Earth’s processes by human factors will construe his spot in the stratigraphic chart.

According to the International Commission on Stratigraphy ICS, in order to build a new geochronological hierarchy it is necessary to determine a reference section that allows its global standardization with an interval that exhibits a continuous sedimentation. This required section is referred as the Global Stratotype Section and Point (GSSP).

Humans have produced profound impacts on Mother Earth, these impacts are contemporaneous with the beginning of the development of productive forces and their diversified order/magnitude of scale vs. natural forces. Human work force empowering might be the basal unconformity for the Anthropocene we oversee, by the expanding technologies and growing populations that demand more natural resources extraction that change Earth's cyclicity, such as climate. The subsequent span proposals can be highly detailed and variable in time scales by the interrelationship between the factors controlling the force-sources. If it is true, such chances must be printed on the stratigraphic record, enabling to set the required GSSP for the Anthropocene establishment.

The development of productive forces generates a specific cultural record, which contributes to denote the state-of-the-art in scientific knowledge about geological sciences with its chronostratigraphic methodology to define time boundaries. This makes possible to spot a new geological epoch with real humanism character, by crossing from a prehistory into the human history by the benefic function of science that contributes to identify Earth's age strata and our rational evolution for the Common Good of the Earth and Humanity.
