Discussion Overview

The discussion revolves around two questions related to geophysics, specifically focusing on magnetic methods and gravimetry. The first question seeks to classify magnetic susceptibility minerals and their characteristics, particularly those containing iron. The second question addresses the density of various rocks and soils, asking for a ranking from lowest to highest density based on their mineral composition and porosity.

Discussion Character

  • Homework-related
  • Conceptual clarification

Main Points Raised

  • The first question asks for the classification of magnetic susceptibility minerals into three groups, requesting their names and characteristics, particularly regarding iron-containing minerals.
  • The second question involves ranking different types of rocks and soils by density, considering factors such as mineral composition and porosity.
  • Some participants express frustration with the original poster for not demonstrating prior effort in addressing the questions.
  • One participant emphasizes the importance of adhering to forum rules, which require users to show their attempts before receiving assistance.

Areas of Agreement / Disagreement

Participants generally agree on the necessity for the original poster to show prior effort before receiving help. However, there is a disagreement regarding the tone of the responses, with some perceiving them as unkind.

Contextual Notes

The discussion lacks specific attempts or answers from the original poster, which may limit the ability of participants to provide targeted assistance. The responses also highlight a potential misunderstanding of forum etiquette.

Hello, Could you tell me help with two questions, please

The question reads as follows:

1) Magnetic methods: According magnetic values
matic susceptibility minerals can be classified into three
basic groups that have their names. Bring
designation of these groups and their most basic
characteristic. Do that holding (s) groups fall Mi-
Neral containing iron? corroborate concretely

2) Gravimetry. The density of rocks and soil depends on the density of minerals, which constitute them further
porosity, and, finally, the proportion of pores filled with air and aqueous solutions. reports fol-
ing rocks in a series from lowest to highest density:

sandstone - basalt - quartz sand - Granite - amphibolite with 30% magnetite - Clay

Thank you very much for your help..

Why are you all so cruel...
 
We are not being cruel. Some day, you will be mining an asteroid by surgical emplacement of small nuclear charges. Your partner, my grand-child, will be assisting from her own spacesuit, just a metre away. You want to be sure that you know what you're doing, right?

When you signed up, you acknowledged that you read the forum rules and would abide by them. And so did we. We are not allowed to help unless you show an effort first.
