THE AGE OF THE EARTH - THE OLDEST MAN ON EARTH IS THE EARTH



THE AGE OF THE EARTH

Hey… Just as we celebrate our birthdays to commemorate the day we were born, has it ever occurred to you to ponder on the age of the earth? Don’t you think that there was a day (way back) when the earth was formed?
Don’t get it twisted!!! This is no myth. It is a reality. It is REAL!!!






The Earth is approximately 4.6 billion years old!!! Sounds absurd???
Well, this figure did not come as a result of fiction or imagination – but by radiometric dating in the early 20th century. Lead in uranium-rich minerals when dated by early scientists,  were able to discover that they were billions of years old.
Another pointer to this is that small crystals of Zircon obtained from Jack Hills, Western Australia when dated, was around 4.4 billion years old.
One may ask: “How is this possible”?
Rocks are aggregate of minerals. Some of these minerals have radioactive elements like Uranium and Thorium. In the process of their decay (radioactive decay), other elements are formed which are stable.
The age of a rock (which has a radioactive element) can be calculated from the information gotten from the measurement of the concentration of the stable end product of the decay of that radioactive element and its initial concentration (i.e. the initial concentration of the decaying element) provided that its half life is known.

  1. What is the formula for calculating half-life?

  2. Sometimes don't you feel like going back in time and seeing how the earth used to be

    1. Yea. I feel. Infact the beauty of geology is that the present is the key to the past

COMPARISON BETWEEN SCHLUMBERGER ARRAY OVER WENNER ARRAY

COMPARISON   BETWEEN SCHLUMBERGER ARRAY OVER WENNER ARRAY Find below the pros and cons of Schlumberger Array over Wenner Array and vice versa Are you a young geologist? Click HERE NOW!!! Advantages of using Schlumberger Array over Wenner                 It requires less manpower and time than Wenner soundings.                 It is less sensitive to lateral variations in resistivity. The potential electrodes are moved only occasionally; In a Wenner sounding the potential and the current electrodes are always moved after each measurement. It is faster in field operation. Types of VES Curves Requires less physical movement of electrodes than the normal Wenner array because only the current electrodes must be moved between readings. The effects of near surface, lateral inhomogeneities are less on Schlumberger measurements when compared to Wenner measurements. In industrial areas, stray currents and telluric currents that a

Vasquez Rocks

Have you heard of Vasquez Rock? Credit: The above picture will be alien except to those within the vicinity of Aqua Dulce, California or perhaps, those that have visited here at one time or the other. Just watch the arcs and the angles formed by this deposit!! In case you do not know, the image you are seeing is Vasquez Rocks. Am fascinated about the arcs and the acute angles formed by this deposit.. Your groundwater may be polluted!!! Nature is indeed wonderful!!!! For emphasis sake, this is in Aqua Dulce, California, north of Los Angeles. Research has it that the ‘arcs’ formed (i.e. tilting was as a result of the North American Plate collision with the Pacific Plate) along the San Andreas fault. We can see that the collision resulted in the uplift.

Lead in Drinking / Groundwater

Possible sources of lead in groundwater Places well known for lead-zinc (Pb-zn) deposits are in danger of having their groundwater contaminated with Lead. Lead is a known silent killer especially in infants and children as it has high affinity for Hemoglobin. Another reason it is a silent killer is because it accumulates (bioaccumulation) in the body gradually stealthily. The fatality of lead is that it gets stored in the bones (as Calcium is stored) and becomes part of the body. From there, it gets released directly into the body. Pregnant and nursing women are the most hit because the Calcium which their bodies require for the growth of the fetus and for breast milk production may be mixed with Lead. The detrimental effects of lead are enormous and felt among infants / children, pregnant women and adults. Among the children , these (but not limited to the following) are pronounced: Ø   Anemia Ø   Slowed / stunted growth Ø   Poor body development Ø   Poor i
