Geological Survey Ireland


Deadline for entry is Friday 28 August, so get out there and get snapping while following HSE guidelines. From pencil and paper to drones and satellites — Geological Survey Ireland Celebrates its th Birthday. Are you curious about Earth, how it works and how it affects our daily lives? Our Education section spills the details. You can visit our customer centre in our offices or access our online shop to browse our products and much more.

Geology is the study of planet Earth — the materials of which it is made, the processes that modify these materials, the resulting products, and the history of the planet and the life forms it has sustained since its formation c. Geology considers the physical forces that act on the Earth, the chemistry of its constituent materials including rocks, minerals, soils and water, and the biology of its past inhabitants as revealed by fossils.

Fossilized, dinner-plate size, algal mounds stromatolites of the Rocknest Formation as exposed at Port Epworth Nunavut , western Canadian Arctic. The dolomitic strata of the Rocknest Formation are between — million years old. Stromatolites, here preserved in life position, constitute some of the earliest traces of life itself on Planet Earth. During the latter part of the 20th Century a key new paradigm — plate tectonics — revolutionized geology by providing an explanation for the longevity of continental crust, the transitory nature of oceans, and the origin of mountains both young and old.

Geologists do not use carbon-based radiometric dating to determine the age of rocks. Carbon dating only works for objects that are younger.

Wellsite geologists study and classify rock cuttings from oil and gas wells in order to determine how drilling should be started and how it should proceed. As a wellsite geologist, you’ll use specialised tests, core samples and rock-cutting data to build up knowledge of the structure being drilled. As an experienced geologist, you’ll decide when tests should be carried out and, ultimately, when to stop drilling. You’ll send reports and logs of completed drilling to the operations geologist and offer advice to oil company representatives.

You’ll also incorporate health and safety requirements in daily geological operations. Wellsite geologists liaise with drilling engineers, petroleum engineers and mudloggers during the course of projects. You’ll be based on-site and your presence is key at the wellsite. As a wellsite geologist, you’ll need to:. Wellsite geologists are typically self-employed and are usually paid on a day rate basis.

You’re paid as long as drilling activity continues. Salaries vary according to your experience, where you’re working in the world and what type of organisation you work for.

This page has been archived and is no longer updated. Despite seeming like a relatively stable place, the Earth’s surface has changed dramatically over the past 4. Mountains have been built and eroded, continents and oceans have moved great distances, and the Earth has fluctuated from being extremely cold and almost completely covered with ice to being very warm and ice-free. These changes typically occur so slowly that they are barely detectable over the span of a human life, yet even at this instant, the Earth’s surface is moving and changing.

As these changes have occurred, organisms have evolved, and remnants of some have been preserved as fossils.

Geochronology is the science of determining the age of rocks , fossils , and sediments using signatures inherent in the rocks themselves. Absolute geochronology can be accomplished through radioactive isotopes , whereas relative geochronology is provided by tools such as palaeomagnetism and stable isotope ratios. By combining multiple geochronological and biostratigraphic indicators the precision of the recovered age can be improved. Geochronology is different in application from biostratigraphy, which is the science of assigning sedimentary rocks to a known geological period via describing, cataloging and comparing fossil floral and faunal assemblages.

Biostratigraphy does not directly provide an absolute age determination of a rock, but merely places it within an interval of time at which that fossil assemblage is known to have coexisted. Both disciplines work together hand in hand, however, to the point where they share the same system of naming strata rock layers and the time spans utilized to classify sublayers within a stratum. The science of geochronology is the prime tool used in the discipline of chronostratigraphy , which attempts to derive absolute age dates for all fossil assemblages and determine the geologic history of the Earth and extraterrestrial bodies.

By measuring the amount of radioactive decay of a radioactive isotope with a known half-life , geologists can establish the absolute age of the parent material. A number of radioactive isotopes are used for this purpose, and depending on the rate of decay, are used for dating different geological periods.

Association of American State Geologists. Adapted with permission. In part, they measure the age of rocks and other natural materials by dating techniques. Geologists use a dating technique called K-Ar geochronology to find the age of layers of volcanic ash in ice cores. The half-life of K-Ar is 1. By measuring the ratio of K to Ar in feldspar crystals in volcanic ash, geologists can determine the time of the eruption and, thus, the age of ice in which the ash is found.
