Potassium Argon Dating Tagalog
By knowing how much carbon is left in a sample, the age of the organism and when it died can be worked out. Radiocarbon dating has been used extensively since its discovery. Examples of use include analyzing charcoal from prehistoric caves, ancient linen and wood, and mummified remains. It is often used on valuable artwork to confirm authenticity. For example, look at this image of the opening of King Tutankhamen’s tomb near Luxor, Egypt during the s.
Potassium—argon dating , abbreviated K—Ar dating , is a radiometric dating method used in geochronology and archaeology. It is based on measurement of the product of the radioactive decay of an isotope of potassium K into argon Ar. Potassium is a common element found in many materials, such as micas , clay minerals , tephra , and evaporites.
In these materials, the decay product 40 Ar is able to escape the liquid molten rock, but starts to accumulate when the rock solidifies recrystallizes. The amount of argon sublimation that occurs is a function of the purity of the sample, the composition of the mother material, and a number of other factors. Time since recrystallization is calculated by measuring the ratio of the amount of 40 Ar accumulated to the amount of 40 K remaining.
The long half-life of 40 K allows the method to be used to calculate the absolute age of samples older than a few thousand years. The quickly cooled lavas that make nearly ideal samples for K—Ar dating also preserve a record of the direction and intensity of the local magnetic field as the sample cooled past the Curie temperature of iron.

Hypertension – or high blood pressure – affects millions of Americans. Endocrine hypertension is a subset of hypertension caused by hormone imbalance, most frequently involving the pituitary or adrenal gland. Patients who develop hypertension before the age of 30 who have a strong family history of hypertension, adrenal tumors, or develop a low potassium level hypokalemia should be screened for endocrine hypertension.
Patients who have poor blood pressure control despite taking three or more blood pressure medications resistant hypertension should also be screened. Endocrine hypertension can be caused when glands produce too much or not enough hormone, or when they are affected by tumors.
Jump to content. Potassium iodide is used to thin mucus and loosen congestion in people with chronic breathing problems that can be complicated by thick mucus in the respiratory tract. Potassium iodide can cause thyroid problems, high potassium levels in your blood, or iodide poisoning. Call your doctor at once if you have swelling in your neck or throat, chest pain, irregular heart rate, muscle weakness, tingly feeling, pain or burning in your mouth, severe headache, or eye irritation.
Potassium iodide can be used as an expectorant to thin mucus and loosen congestion in your chest and throat. Potassium iodide is used in people with chronic breathing problems that can be complicated by thick mucus in the respiratory tract, such as asthma, chronic bronchitis, or emphysema. You should not use this medication if you have a history of previous allergic reaction to iodide, iodine, or other medicines.
FDA pregnancy category D. Do not use potassium iodide if you are pregnant. It could harm the unborn baby. Use effective birth control, and tell your doctor if you become pregnant during treatment. Potassium iodide can pass into breast milk and may harm a nursing baby. You should not breast-feed while using this medicine.

There are three principal islands, all of volcanic origin 2 : Masatierra [is approx. The islands and several submerged seamonts near 33[deg. The Juan Fernandez Ridge does not appear to be related to other features of the Nazca plate ocean floor, and it has been suggested that the islands are the products of isolated intraplate volcanism 4 , perhaps associated with a hot spot. The archipelago has native species of flowering plants, 69 percent of which are endemic 5 , including the monotypic family Lactoridaceae.
The flora has been extensively described by Skottsberg and his co-workers Our our investigation of the patterns of phylogeny and the modes of speciation in the endemic taxa, it was necessary first to determine the ages of the islands. Bruggen 10 had suggested an Eocene age for the hypothetical Sierra de juan Fernandez Ridge, which presumably extended from continental Chile out to the islands.
The archipelago was thought to have fromed by more recent volcanic activity, and subsequent subsidence of the ridge left the islands isolated by water. This was the geologic perspective that Skottsberg 5 used in explaining the presence of distinct endemic genera with apparent ancient affinities such as Lactoris. The ocean floor in the vicinity is of Eocene age Baker 12 concluded that the landforms indicated a late Tertiary age and potassium-argon dating of a sample of dolerite gave an age of approximately 5 million years m.

The Eskinol left behind a cool, astringent sensation on my skin. As I rubbed the whitener onto my face with a cotton ball, I closed my eyes and imagined scouring away layers of brown skin, leaving behind a luminous pallor, like washing grime off china. My mother is Filipina, and I inherited her dusky kayumanggi complexion. If anything, it often drew praise from my friends, mostly white, who would have gladly traded their sunburns for my year-round tan. But in college, I found a thriving community of Filipino-American students, including my former boyfriend.
I was drawn to his goofy humor and laid-back personality, which smoothed out my own serious, anxious edges. He was born in the Philippines, spoke Tagalog, and avidly followed Filipino pop culture. On our first few dates, we listened to Tagalog songs on his iPhone and ate at local Filipino restaurants.

Potassium-argon dating , method of determining the time of origin of rocks by measuring the ratio of radioactive argon to radioactive potassium in the rock. This dating method is based upon the decay of radioactive potassium to radioactive argon in minerals and rocks; potassium also decays to calcium Thus, the ratio of argon and potassium and radiogenic calcium to potassium in a mineral or rock is a measure of the age of the sample. The calcium-potassium age method is seldom used, however, because of the great abundance of nonradiogenic calcium in minerals or rocks, which masks the presence of radiogenic calcium.
On the other hand, the abundance of argon in the Earth is relatively small because of its escape to the atmosphere during processes associated with volcanism. The potassium-argon dating method has been used to measure a wide variety of ages.
