The flux of quarks in air shower cores at sea level is estimated from four different types of experiments. All four estimates agree and yield a quark flux of 8 x 10-12 cm-2 s- 1 sr- 1 ? The calculated concentration of quarks in the Earth's crust resulting from this flux is compared with that found in niobium in the Stanford quark search.

Earth's Crust

Rare earth metals are used in electricity, electronics, nuclear, optics, space, metallurgy,superconducting and super magnetic materials, glass and ceramics, and agriculture. Some rare earthelements are added to fertilizers for crops and some trials for animal feed. Rare earth elements, exceptfor radioactive promethium, are relatively abundant in the earth's crust. Vietnam has a tremendous rareearth potential, distributed mainly in the Northwest, including Nam Xe, Dong Pao, Muong Hum, andYen Bai. There are many research projects on rare earth ores of different types globally, but the focus ismainly on the essential minerals, including monazite, xenotime, and bastnaesite. This report summarizesresearch data on rare earth ore intending to produce a general assessment of rare earth ore and itsbeneficiation technology in Vietnam.

Gravitational Equilibrium

Earthquake is a series of vibrations within the earth's crust. It occurs when the earth's crust break due to geological forces on the rock and adjoining plate. Earthquake refers to a movement or tremor of the earth’s crust that originates naturally and below the surface. An earthquake is a vibration or oscillation of the surface of the earth caused by a transient disturbance of the elastic or gravitational equilibrium of the rocks at or beneath the surface. There are two causes of earthquakes. One is religious concept and the other is modern concept. Earthquakes are of different types according to their place of origin and location. There are so many effects of earthquakes.The Himalayan Physics Vol. 6 & 7, April 2017 (86-91)

The Moment

The unresolved problem of traditional seismology to date is the separation from the stream of information recorded by numerous seismic sensors of a strictly defined signal about the approach of a catastrophic earthquake specific in time and space. Such a signal is usually lost against a constant background from a large number of another events. At the turn of the 1980s and 1990s, scientists from the Physics Institute and the Institute of Physics of the Earth developed a preliminary concept for a new promising direction in seismology. Using the signal from elastic vibrations in the acoustic frequency range for earthquake prediction. These signals can be generated by ionization. Ionization is formed at the moment of the passage of high-energy muons through a seismically stressed medium in the deep layers of the earth's crust. It is hoped that this method may be one way to predict earthquakes in the future.

Shower Array

The shielded 60-m2 scintillation detector in the center of the Chacaltaya air shower array was used to observe large bursts of size greater than 3 000 particles. These bursts are produced mainly by nuclear interactions in the absorber above the scintillator of nuclear-active particles with energy greater than 3 × 1012 eV. The majority of these bursts are accompanied by extensive air showers, which were detected by the BASJE array. However, there are some events which are not accompanied by air showers and are considered to be due to residual primary nucleons. Some features of the data and results of preliminary analysis of these events will be presented.

It is unnecessary for me to remind the readers of the Geological Magazine of the evidence for elevation and subsidence. For my present purpose it is sufficient to remind them that suoh elevation and subsidence has been attributed (1) to lateral pressure giving rise to long geo-anticlines and geo-synclines; (2) to expansion and contraction of the underlayers resulting from a rise or a fall of temperature; and (3) to the loading and unloading of the areas of the earth's crust affected. Apparent elevation and subsidence, which we may here neglect, may be due to a rise or fall of the sea-level such as is dealt with by Prof. Hull in a recent communication to this Magazine.
