The paredon, Mexico, obsidian source and early formative exchange
Science (New York, N.Y.)
|September 1, 1978
Summary
Archeological surveys rediscovered a pre-Hispanic obsidian source in central Mexico. Trace element analysis revealed that Paredón obsidian, not Otumba, was crucial during the Early Formative period.
Area of Science:
- Archaeology
- Geochemistry
- Material Science
Background:
- The Paredón obsidian source in central Mexico was initially reported in 1902.
- Archeological surveys in 1975 re-identified this source along ancient trade routes.
Purpose of the Study:
- To determine the primary obsidian source utilized in central Mexico during the Early Formative period.
- To compare the trace element profiles of obsidian from the Paredón source with obsidian found at Chalcatzingo.
Main Methods:
- Neutron activation analysis (NAA) was employed to study the trace element composition of obsidian samples.
- Surface archeological surveys were conducted to identify and re-locate obsidian sources and associated trade routes.
Main Results:
- Trace element analysis indicated a strong correlation between obsidian from the Paredón source and obsidian artifacts found at Chalcatzingo.
- Obsidian from the Paredón source was found to be of primary importance during the Early Formative period in central Mexico.
Conclusions:
- The Paredón obsidian source was a significant contributor to the material culture of central Mexico during the Early Formative.
- Obsidian sourcing studies using NAA are crucial for understanding ancient trade networks and resource utilization.

02:06Social Exchange Theory
26.2K
We have discussed why we form relationships, what attracts us to others, and different types of love. But what determines whether we are satisfied with and stay in a relationship? One theory that provides an explanation is social exchange theory. According to social exchange theory, we act as naïve economists in keeping a tally of the ratio of costs and benefits of forming and maintaining a relationship with others (Rusbult & Van Lange, 2003).

01:17Ion Exchange
1.6K
Ion exchange chromatography separates charged molecules from a solution by reversibly exchanging them with mobile, or 'active', ions associated with the oppositely charged stationary phase. This method can be used to separate ions, soften and deionize water, and purify solutions. The polymers comprising the ion-exchange column are high-molecular-weight and chemically stable polymers, crosslinked to be porous and essentially insoluble. They are also functionalized with either acidic or...

In brick wall construction, supporting structures are crucial for openings like windows and doors to maintain the integrity and support the weight of the wall above. These supports include lintels, corbels, and arches, each serving specific structural purposes.
Lintels are primary supports used to span openings and can be crafted from materials such as reinforced concrete, steel-reinforced brick masonry, or simple steel angles. These are straightforward to install and are typically concealed...

Quarrying is the process of extracting stone from a quarry, where specialized techniques are employed to remove large blocks of stone safely and efficiently. This process can involve controlled explosions or more precision-oriented methods such as cutting and drilling.
One common method involves using a diamond belt saw to cut large blocks from the quarry face. These blocks can be about 50 feet long and 12 feet high. After the initial vertical cut, drilling is performed at the base of the...

01:20Porosity and Absorption of Aggregate
1.0K
Aggregates contain pores of varying sizes; while some are completely enclosed within the particles, others open onto the surface, allowing water to penetrate. The porosity of aggregates is a major factor contributing to the overall porosity of concrete, given that aggregates constitute about three-quarters of concrete's volume.
When all pores in an aggregate are filled with water, the aggregate is considered saturated and surface-dry. If left in dry air, water will evaporate until the...

As formulated by John Thibaut and Harold Kelley, Social Exchange Theory explains human relationships as economic-like exchanges that maximize rewards and minimize costs. This theory suggests that individuals engage in relationships to gain benefits and reduce burdens, similar to economic transactions. It has been widely applied to various types of relationships, including romantic, professional, and social interactions.Rewards and Costs in RelationshipsRelationship rewards include emotional...
