Thanks Prof.Amrit

Dear Abdelhakim Eshanibli ,

Your is question is great...

According to the currently accepted gravity, it could be extracted density values from gravity data points... however, in reality it does not work that way. Because the current theory of gravity does not adequately represent the real situation...

I know because I worked for 8 years as a geologist engineer in petroleum and natural gas research. When the theory looks good, it is due to accidentally enviroment.

You know well that the situation is not so simple..

To use the gravity you need an geological model developed by me (no published)...,

and get ideas for free from the next discussion (question):

We know very well that in many cases they teach amazing things at universities! (I'm not a professor... that's why I don't want to teach; But if someone wants to learn from me, I can do it as a private teacher )

Thank you prod. Laszlo

There is something called number count density.

I am not sure about what kind of data you have, or your aims, but gravimetry is an area of geophysics that studies the components of gravity acceleration. So we start with a series of g data and finish the calculations with free-air or Bouguer anomalies. Then, we use these anomalies to estimate the density of the crustal/lithospheric source by modeling. A very good book to understand gravimetry is the "potential theory in gravity and magnetic applications" by Blakely. You can also calculate a better value for the Bouguer correction, if your purpose is to estimate the density for a hole area, there are many possibilities actually, but as none of the answers before me used gravimetry to help you, I am not sure if this is what you were expecting. If you need further recommendations, please contact me.

Thank you Dr.Denise

I will explain to you privately later

Thank you so much

In geophysical prospecting (which is an interdisciplinary branch of physics and geosciences) we usually acquire the acceleration of the earth gravitational field in sense of gravity readings, then we use simple mass-gravity Newtonian conversion as in Newton's law of gravity (which is described by Talwani et al. 1959 (Article Rapid Gravity Computations for Two-Dimensional Bodies with A...

hello i think using 2D 3D inversion process

Greetings to you dear Abdelhakim

You know that the interpretation in gravity studies mainly deal with the residual gravity anomaly. This means that the original gravity data respected to many corrections to get the Bouguer gravity map. The Bouguer gravity maps processes to seperat the residual gravity from regional gravity in order to get as possible as an isolated gravity anomalies. The isolated gravity anomalies can be interpreted easily. The major problem in gravity interpretation as the other geophysical is the ambiguity. No one, No methods can used to know actual distribution of density of any source. All the geophysical methods including gravity methods attempt to solve the actual figure of the subsurface sources. But all methods still an estimated methods. The improvement in the processing methods and the advance programs may be make the calculation easier and faster and the approximation better, but the ambiguity still effective. The approximation of density distribution, which gives a model nearly coincide the geological model with an error of 10-15 % is accepted now.The unit density modeling can give good result, but it is still an approximation method.

With best regards

Thank you Dr. Ahmed

Hi, you need to check first if your data is corrected or not. After correction of gravity data, you need to calculate Bouguer anomaly. After that, you can use a computer code to invert your Bouguer anomaly data to get 3D density model of the subsurface of your study area

Thank you Dr.Hakim for this answer

I hope to get your email to contact you and send you some details about the data that I have.

The process is a 2d/3D Gravity inversion process...

Article Earth Gravity is not Newtonian

Gravity does not recognize pressure & Temperature.

Can be extracting relative density not absolute

you have to perform a 3D gravity model ( which is close to the observed model; we called it the predicted model). if you are working on superficial issues, use the residual anomaly and if you are working on the deep structures ( ex: continental margin ) use the Bouguer Anomaly. you can take a look at this book ( Potential Theory in Gravity and Magnetic Applications - Richard J. Blakely), it is very helpful.

good luck,

) and get this 2D simple gravity modeller (http://fastgrav.com/) or ''https://gif.eos.ubc.ca/software/utility_programs'' for 3D gravity modeling) to draw the underground earth's subsurface, so technically you can convert your gravity csv data into density readings by refering to these software.
